%\section{Introduction}
%
%The \clsfmt{jmlr} class is for articles that need to be formatted
%according to the Journal of Machine Learning Research style. This
%class is based on the \sty{jmlr2e} and \sty{jmlrwcp2e} packages
%but has been adapted to enable it to work better with the
%\cls{combine} class to collate the articles into a book.
%\sectionref{sec:jmlr} describes how to use the \clsfmt{jmlr} class.
%
%The \clsfmt{jmlrbook} class is for combining JMLR articles into a book.
%This class uses \cls{combine} and \sty{hyperref}, which are
%troublesome enough on their own but together are quite fragile. The
%\clsfmt{jmlrbook} class redefines some internals to get \clsfmt{combine}
%and \clsfmt{hyperref} to work together but some packages (e.g.\
%\sty{subfig} and \sty{pdfpages}) are likely to mess everything up
%and cause errors. This is why the guidelines to authors are fairly
%stringent and why \clsfmt{jmlr} will give an error message if certain
%packages are loaded.\footnote{Currently \clsfmt{jmlr} will check if
%\sty{subfig}, \sty{pdfpages}, \sty{geometry}, \sty{psfig},
%\sty{epsfig} and \sty{theorem} are loaded and will throw an error.
%If other packages are found to be a problem, they will be added to
%the list.} The \clsfmt{jmlrbook} class works best with PDF\LaTeX\ so
%authors should ensure that their articles can compile with
%PDF\LaTeX. \sectionref{sec:jmlrbook} describes how to use the
%\clsfmt{jmlrbook} class.
%
%The \app{makejmlrbook} Perl script can be used to make a book that
%uses the \clsfmt{jmlrbook} class. In addition to creating the print
%and online versions of the book, it will compile the individual
%articles, running Bib\TeX\ where necessary, and create a set of
%HTML files containing a list of all the articles imported into the
%book along with links to the abstracts and PDFs of the individual
%articles. \sectionref{sec:makejmlrbook} describes how
%to use the \app{makejmlrbook} application.
%
%\section{Required Packages}
%
%The \clsfmt{jmlr} class is based on the \cls{scrartcl} class and loads
%the following packages: \sty{amsmath}, \sty{amssymb},
%\sty{natbib}, \sty{url}, \sty{graphicx} and \sty{algorithm2e}.
%Note that unlike the \sty{jmlr2e} and \sty{jmlrwcp2e} packages,
%this class file does not load the obsolete \sty{epsfig} package.
%
%The \clsfmt{jmlrbook} class additionally loads the \cls{combine} class
%and the following packages: \sty{hyperref}, \sty{xkeyval},
%\sty{combnat} and \sty{setspace}.
%
%The \app{makejmlrbook} script requires Perl, \TeX\ and \TeX4ht.
%
%\section{Guidelines for Article Authors}
%\label{sec:jmlr}
%
%Article authors should use the \clsfmt{jmlr} class. This class
%comes with example files \texttt{jmlr-sample.tex} and
%\texttt{jmlrwcp-sample.tex}, which can be used as templates.
%
%The following class options are available:
%\begin{description}
%\item[\clsopt{nowcp}]The article is for the Journal of Machine
%Learning Research (default).
%\item[\clsopt{wcp}] The article is for JMLR Workshop and Conference
%Proceedings.
%
%\item[\clsopt{twocolumn}] Use two-column style.
%
%\item[\clsopt{onecolumn}] Use one-column style (default).
%
%\item[\clsopt{color}] Color version (see \sectionref{sec:color}).
%
%\item[\clsopt{gray}] Grayscale version (see \sectionref{sec:color}).
%
%\item[\clsopt{tablecaptiontop}] in a \env{table} environment,
%\ics{floatconts} puts the caption at the top.
%
%\item[\clsopt{tablecaptionbottom}] in a \env{table} environment,
%\ics{floatconts} puts the caption at the bottom.
%\end{description}
%
%\subsection{Title Information}
%
%The \clsfmt{jmlr} class uses different syntax from \sty{jmlr2e} and
%\sty{jmlrwcp2e} to specify the title information. In particular, it
%doesn't define \cs{jmlrheading} and \cs{ShortHeading}. Instead, the
%following commands should be used:
%
%\begin{definition}[\DescribeMacro{\jmlrvolume}]
%\cs{jmlrvolume}\marg{number}
%\end{definition}
%This specifies the volume number. For example:
%\begin{verbatim}
%\jmlrvolume{2}
%\end{verbatim}
%
%\begin{definition}[\DescribeMacro{\jmlryear}]
%\cs{jmlryear}\marg{year}
%\end{definition}
%This specifies the year. For example:
%\begin{verbatim}
%\jmlryear{2010}
%\end{verbatim}
%
%\begin{definition}[\DescribeMacro{\jmlrsubmitted}]
%\cs{jmlrsubmitted}\marg{date}
%\end{definition}
%This specifies the submission date.
%
%\begin{definition}[\DescribeMacro{\jmlrpublished}]
%\cs{jmlrpublished}\marg{date}
%\end{definition}
%This specifies the publication date.
%
%\begin{definition}[\DescribeMacro{\jmlrworkshop}]
%\cs{jmlrworkshop}\marg{title}
%\end{definition}
%This specifies the workshop title (for use with the \clsopt{wcp}
%class option).
%
%The title information is specified using the commands described
%below. These commands should typically go in the preamble. As
%with most class files, The title itself is produced using
%\begin{definition}[\DescribeMacro{\maketitle}]
%\cs{maketitle}
%\end{definition}
%This command should go after \verb|\begin{document}|. For example:
%\begin{verbatim}
%\begin{document}
%\maketitle
%\end{verbatim}
%Before \cs{maketitle}, you must specify the title information
%using the following commands:
%
%\begin{definition}[\DescribeMacro{\title}]
%\cs{title}\oarg{short title}\marg{title}
%\end{definition}
%This specifies the article's title. A short title for the page
%header can be supplied via the optional argument \meta{short title}.
%
%\begin{definition}[\DescribeMacro{\editor}]
%\cs{editor}\marg{name}
%\end{definition}
%This specifies the editor's name. If there is more than one
%editor, use:
%\begin{definition}[\DescribeMacro{\editors}]
%\cs{editors}\marg{names}
%\end{definition}
%
%\begin{definition}[\DescribeMacro{\author}]
%\cs{author}\marg{author specs}
%\end{definition}
%This specifies the author. The specifications \meta{author specs}
%are a bit different to \sty{jmlr2e} and \sty{jmlrwcp2e}. Use
%\begin{definition}[\DescribeMacro{\Name}]
%\cs{Name}\marg{author's name}
%\end{definition}
%to specify the author's name. Note that if the surname contains a
%space it must be grouped (enclosed in braces \{\}). Similarly if
%the initial letter of each forename is a diacritic it must be
%grouped. (See below for examples.)
%\begin{definition}[\DescribeMacro{\Email}]
%\cs{Email}\marg{author's email}
%\end{definition}
%This specifies the author's email address. It should only be used
%within the argument to \cs{author}.
%
%\begin{definition}[\DescribeMacro{\and}]
%\cs{and}
%\end{definition}
%This should be used to separate two authors with the same address.
%
%\begin{definition}[\DescribeMacro{\AND}]
%\cs{AND}
%\end{definition}
%This should be used to separate authors with different addresses.
%
%\begin{definition}[\DescribeMacro{\\}]
%\verb|\\|
%\end{definition}
%This should be used before an author's address or between authors
%with the same address where there are more that two authors.
%
%\begin{definition}[\DescribeMacro{\addr}]
%\cs{addr}
%\end{definition}
%This should be used at the start of the address.
%
%\begin{description}
%\item[Example 1] Two authors with the same address:
%\begin{verbatim}
%\author{\Name{Jane Doe} \Email{abc@sample.com}\and
% \Name{John {Basey Fisher}} \Email{xyz@sample.com}\\
% \addr Address}
%\end{verbatim}
%In this example, the second author has a space in his surname
%so the surname needs to be grouped.
%
%\item[Example 2] Three authors with the same address:
%\begin{verbatim}
%\author{\Name{Fred Arnold {de la Cour}} \Email{an1@sample.com}\\
% \Name{Jack Jones} \Email{an3@sample.com}\\
% \Name{{\'E}louise {\'E}abhla Finchley} \Email{an2@sample.com}\\
% \addr Address}
%\end{verbatim}
%In this example, the third author has an accent on her
%forename initials so grouping is required.
%
%\item[Example 3] Authors with a different address:
%\begin{verbatim}
%\author{\Name{John Smith} \Email{abc@sample.com}\\
% \addr Address 1
% \AND
% \Name{May Brown} \Email{xyz@sample.com}\\
% \addr Address 2
% }
%\end{verbatim}
%\end{description}
%
%\subsection{Font Changing Commands}
%
%Use the \LaTeXe\ font changing commands, such as \cs{bfseries} or
%\cs{textbf}\marg{text}, rather than the obsolete \LaTeX2.09
%commands, such as \cs{bf}.
%
%\begin{definition}[\DescribeMacro{\url}]
%\cs{url}\marg{address}
%\end{definition}
%This will typeset \meta{address} in a typewriter font. Special
%characters, such as \verb|~|, are correctly displayed. Example:
%\begin{verbatim}
%\url{http://theoval.cmp.uea.ac.uk/~nlct/}
%\end{verbatim}
%
%\begin{definition}[\DescribeMacro{\mailto}]
%\cs{mailto}\marg{email address}
%\end{definition}
%This will typeset the given email address in a typewriter font.
%Note that this is not the same as \cs{Email}, which should only be
%used in the argument of \cs{author}.
%
%\subsection{Structure}
%
%\begin{definition}[\DescribeEnv{abstract}]
%\cs{begin}\{abstract\}\\
%\meta{text}\\
%\cs{end}\{abstract\}
%\end{definition}
%The abstract text should be displayed using the \envfmt{abstract}
%environment.
%
%\begin{definition}[\DescribeEnv{keywords}]
%\cs{begin}\{keywords\}\meta{keyword list}\cs{end}\{keywords\}
%\end{definition}
%The keywords should be displayed using the \envfmt{keywords}
%environment.
%
%\begin{definition}[\DescribeMacro{\acks}]
%\cs{acks}\marg{text}
%\end{definition}
%This displays the acknowledgements.
%
%\begin{definition}[\DescribeMacro{\section}]
%\cs{section}\marg{title}
%\end{definition}
%Section titles are created using \cs{section}. The heading is
%automatically numbered and can be cross-referenced using
%\cs{label} and \cs{ref}. Unnumbered sections can be produced
%using:
%\begin{definition}[\DescribeMacro{\section*}]
%\cs{section*}\marg{title}
%\end{definition}
%
%\begin{definition}[\DescribeMacro{\subsection}]
%\cs{subsection}\marg{title}
%\end{definition}
%Sub-section titles are created using \cs{subsection}. Unnumbered
%sub-sections can be produced using:
%\begin{definition}[\DescribeMacro{\subsection*}]
%\cs{subsection*}\marg{title}
%\end{definition}
%
%\begin{definition}[\DescribeMacro{\subsubsection}]
%\cs{subsubsection}\marg{title}
%\end{definition}
%Sub-sub-section titles are created using \cs{subsubsection}.
%Unnumbered sub-sub-sections can be produced using:
%\begin{definition}[\DescribeMacro{\subsubsection*}]
%\cs{subsubsection*}\marg{title}
%\end{definition}
%
%Further sectioning levels can be obtained using \cs{paragraph}
%and \cs{subparagraph}, but these are unnumbered with running heads.
%
%\begin{definition}[\DescribeMacro{\appendix}]
%\cs{appendix}
%\end{definition}
%Use \cs{appendix} to switch to the appendices. This changes
%\cs{section} to produce an appendix. Example:
%\begin{verbatim}
%\appendix
%\section{Proof of Theorems}
%\end{verbatim}
%
%\subsection{Citations and Bibliography}
%
%The \clsfmt{jmlr} class automatically loads \sty{natbib} and sets
%the bibliography style to \texttt{plainnat}. References should
%be stored in a \texttt{.bib} file.
%
%\begin{definition}[\DescribeMacro{\bibliography}]
%\cs{bibliography}\marg{bib file}
%\end{definition}
%This displays the bibliography.
%
%\begin{definition}[\DescribeMacro{\citep}]
%\cs{citep}\oarg{pre note}\oarg{post note}\marg{label}
%\end{definition}
%Use \cs{citep} for a parenthetical citation.
%
%\begin{definition}[\DescribeMacro{\citet}]
%\cs{citet}\oarg{note}\marg{label}
%\end{definition}
%Use \cs{citet} for a textual citation.
%
%See the \ctandoc{natbib} for further details.
%
%\subsection{Figures and Tables}
%
%Floats, such as figures, tables and algorithms, are moving objects
%and are supposed to float to the nearest convenient location.
%Please don't force them to go in a particular place. In general
%it's best to use the \texttt{htbp} specifier and don't put
%the float in the middle of a paragraph (that is, make sure there's
%a paragraph break above and below the float). Floats are supposed
%to have a little extra space above and below them to make them
%stand out from the rest of the text. This extra space is put in
%automatically and shouldn't need modifying.
%
%To ensure consistency, please \emph{don't} try changing the
%format of the caption by doing something like:
%\begin{verbatim}
%\caption{\textit{A Sample Caption.}}
%\end{verbatim}
%or
%\begin{verbatim}
%\caption{\em A Sample Caption.}
%\end{verbatim}
%You can, of course, change the font for individual words or
%phrases. For example:
%\begin{verbatim}
%\caption{A Sample Caption With Some \emph{Emphasized Words}.}
%\end{verbatim}
%
%The \clsfmt{jmlr} class provides the following command for displaying
%the contents of a figure or table:
%\begin{definition}[\DescribeMacro{\floatconts}]
%\cs{floatconts}\marg{label}\marg{caption command}\marg{contents}
%\end{definition}
%This ensures that the caption is correctly positioned and that
%the contents are centered. For example:
%\begin{verbatim}
%\begin{table}[htbp]
%\floatconts
% {tab:example}% label
% {\caption{An Example Table}}% caption command
% {%
% \begin{tabular}{ll}
% \bfseries Dataset & \bfseries Result\\
% Data1 & 0.123456
% \end{tabular}
% }
%\end{table}
%\end{verbatim}
%
%The \clsfmt{jmlr} class automatically loads \sty{graphicx} which
%defines:
%\begin{definition}[\DescribeMacro{\includegraphics}]
%\cs{includegraphics}\oarg{options}\marg{file name}
%\end{definition}
%where \meta{options} is a comma-separated list of options.
%
%For example, suppose you have an image called
%\texttt{mypic.png} in a subdirectory called \texttt{images}:
%\begin{verbatim}
%\begin{figure}[htbp]
%\floatconts
% {fig:example}% label
% {\caption{An Example Figure}}% caption command
% {\includegraphics[width=0.5\textwidth]{images/mypic}}
%\end{figure}
%\end{verbatim}
%
%Note that you shouldn't specify the file extension when including
%the image. It's helpful if you can also provide a grayscale
%version of color images. This should be labeled as the color
%image but with \texttt{-gray} immediately before the extension.
%(The extension need not be the same as that of the color image.)
%For example, if you have an image called \texttt{mypic.pdf}, the
%grayscale can be called \texttt{mypic-gray.pdf},
%\texttt{mypic-gray.png} or \texttt{mypic-gray.jpg}.
%See \sectionref{sec:color} for further details.
%
%\begin{definition}[\DescribeMacro{\includeteximage}]
%\cs{includeteximage}\oarg{options}\marg{file name}
%\end{definition}
%If your image file is made up of \LaTeX\ code (e.g.\ \sty{tikz}
%commands) the file can be included using \cs{includeteximage}.
%The optional argument is a key=value comma-separated list
%where the keys are a subset of those provided by
%\cs{includegraphics}. The main keys are: \texttt{width},
%\texttt{height}, \texttt{scale} and \texttt{angle}.
%
%\subsubsection{Sub-Figures and Sub-Tables}
%
%The \sty{subfig} package causes a problem for \clsfmt{jmlrbook} so
%the \clsfmt{jmlr} class will give an error if it is used. Therefore
%the \clsfmt{jmlr} class provides its own commands for including
%sub-figures and sub-tables.
%
%\begin{definition}[\DescribeMacro{\subfigure}]
%\cs{subfigure}\oarg{title}\oarg{valign}\marg{contents}
%\end{definition}
%This makes a sub-figure where \meta{contents} denotes the contents
%of the sub-figure. This should also include the \cs{label}.
%The first optional argument \meta{title} indicates a caption for
%the sub-figure. By default, the sub-figures are aligned at the
%base. This can be changed with the second optional argument
%\meta{valign}, which may be one of: \texttt{t} (top), \texttt{c}
%(centred) or \texttt{b} (base).
%
%For example, suppose there are two images files, \texttt{mypic1.png}
%and \texttt{mypic2.png}, in the subdirectory \texttt{images}.
%Then they can be included as sub-figures as follows:
%\begin{verbatim}
%\begin{figure}[htbp]
%\floatconts
% {fig:example2}% label for whole figure
% {\caption{An Example Figure.}}% caption for whole figure
% {%
% \subfigure{%
% \label{fig:pic1}% label for this sub-figure
% \includegraphics{images/mypic1}
% }\qquad % space out the images a bit
% \subfigure{%
% \label{fig:pic2}% label for this sub-figure
% \includegraphics{images/mypic2}
% }
% }
%\end{figure}
%\end{verbatim}
%
%\begin{definition}[\DescribeMacro{\subtable}]
%\cs{subtable}\oarg{title}\oarg{valign}\marg{contents}
%\end{definition}
%This is an analogous command for sub-tables. The default value
%for \meta{valign} is \texttt{t}.
%
%\subsection{Algorithms}
%
%\begin{definition}[\DescribeEnv{algorithm}]
%\cs{begin}\{algorithm\}\\
%\meta{contents}\\
%\cs{end}\{algorithm\}
%\end{definition}
%Enumerated textual algorithms can be displayed using the
%\envfmt{algorithm} environment. Within this environment, use
%\ics{caption} to set the caption (and \ics{label} to cross-reference
%it). Within the body of the environment you can use the
%\env{enumerate} environment.
%
%\begin{definition}[\DescribeEnv{enumerate*}]
%\cs{begin}\{enumerate*\}\\
%\cs{item} \meta{text}\\
%\ldots\\
%\cs{end}\{enumerate*\}
%\end{definition}
%If you want to have nested \env{enumerate} environments but you want
%to keep the same numbering throughout the algorithm, you can use the
%\envfmt{enumerate*} environment, provided by the \clsfmt{jmlr}
%class. For example:
%\begin{verbatim}
%\begin{enumerate*}
% \item Set the label of vertex $s$ to 0
% \item Set $i=0$
% \begin{enumerate*}
% \item \label{step:locate}Locate all unlabelled vertices
% adjacent to a vertex labelled $i$ and label them $i+1$
% \item If vertex $t$ has been labelled,
% \begin{enumerate*}
% \item[] the shortest path can be found by backtracking, and
% the length is given by the label of $t$.
% \end{enumerate*}
% otherwise
% \begin{enumerate*}
% \item[] increment $i$ and return to step~\ref{step:locate}
% \end{enumerate*}
% \end{enumerate*}
%\end{enumerate*}
%\end{algorithm}
%\end{verbatim}
%
%
%\begin{definition}[\DescribeEnv{algorithm2e}]
%\cs{begin}\{algorithm2e\}\\
%\meta{contents}\\
%\cs{end}\{algorithm2e\}
%\end{definition}
%Pseudo code can be displayed using the \envfmt{algorithm2e} environment,
%provided by the \sty{algorithm2e} package, which is automatically
%loaded. For example:
%\begin{verbatim}
%\begin{algorithm2e}
%\caption{Computing Net Activation}
%\label{alg:net}
%\dontprintsemicolon
%\linesnumbered
%\KwIn{$x_1, \ldots, x_n, w_1, \ldots, w_n$}
%\KwOut{$y$, the net activation}
%$y\leftarrow 0$\;
%\For{$i\leftarrow 1$ \KwTo $n$}{
% $y \leftarrow y + w_i*x_i$\;
%}
%\end{algorithm2e}
%\end{verbatim}
%
%See the \ctandoc{algorithm2e} for more details.
%
%\subsection{Description Lists}
%
%\begin{definition}[\DescribeEnv{altdescription}]
%\cs{begin}\{altdescription\}\marg{widest label}\\
%\cs{item}\oarg{label} \meta{item text}\\
%\cs{end}\{altdescription\}
%\end{definition}
%In addition to the standard \env{description} environment, the
%\clsfmt{jmlr} class also provides the \envfmt{altdescription} environment.
%This has an argument that should be the widest label used in the
%list. For example:
%\begin{verbatim}
%\begin{altdescription}{differentiate}
%\item[add] A method that adds two variables.
%\item[differentiate] A method that differentiates a function.
%\end{altdescription}
%\end{verbatim}
%
%\subsection{Theorems, Lemmas etc}
%
%The \clsfmt{jmlr} class provides the following theorem-like
%environments: \env{theorem}, \env{example}, \env{lemma},
%\env{proposition}, \env{remark}, \env{corollary}, \env{definition},
%\env{conjecture} and \env{axiom}. Within the body of those
%environments, you can use the \env{proof} environment to display the
%proof if need be. The theorem-like environments all take an
%optional argument, which gives the environment a title. For example:
%
%\begin{verbatim}
%\begin{theorem}[An Example Theorem]
%\label{thm:example}
%This is the theorem.
%\begin{proof}
%This is the proof.
%\end{proof}
%\end{theorem}
%\end{verbatim}
%
%\subsection{Cross-Referencing}
%\label{sec:crossref}
%
%Always use \ics{label} when cross-referencing, rather than writing
%the number explicitly. The \clsfmt{jmlr} class provides some
%convenience commands to assist referencing. These commands,
%described below, can all take a comma-separated list of labels.
%
%\begin{definition}[\DescribeMacro{\sectionref}]
%\cs{sectionref}\marg{label list}
%\end{definition}
%Used to refer to a section or sections. For example, if you defined
%a section as follows:
%\begin{verbatim}
%\section{Results}\label{sec:results}
%\end{verbatim}
%you can refer to it as follows:
%\begin{verbatim}
%The results are detailed in \sectionref{sec:results}.
%\end{verbatim}
%This command may also be used for sub-sections and sub-sub-sections.
%
%\begin{definition}[\DescribeMacro{\appendixref}]
%\cs{appendixref}\marg{label list}
%\end{definition}
%Used to refer to an appendix or multiple appendices.
%
%\begin{definition}[\DescribeMacro{\equationref}]

%\end{definition}
%Used to refer to an equation or multiple equations.
%
%\begin{definition}[\DescribeMacro{\tableref}]
%\cs{tableref}\marg{label list}

%used for sub-tables where the main table number is also required.
%
%\begin{definition}[\DescribeMacro{\subtabref}]
%\cs{subtabref}\marg{label list}
%\end{definition}
%Used to refer to sub-tables without the main table number, e.g.
%(\emph{a}) or (\emph{b}).
%
%\begin{definition}[\DescribeMacro{\figureref}]
%\cs{figureref}\marg{label list}
%\end{definition}
%Used to refer to a figure or multiple figures. This can also
%be used for sub-figures where the main figure number is also
%required, e.g.\ 2(\emph{a}) or 4(\emph{b}).
%
%\begin{definition}[\DescribeMacro{\subfigref}]
%\cs{subfigref}\marg{label list}
%\end{definition}

%\subsection{Mathematics}
%
%The \clsfmt{jmlr} class loads the \sty{amsmath} package so you can use
%any of the commands and environments defined in that package. A
%brief summary of some of the more common commands and environments
%is provided here. See the \ctandoc{amsmath} for further details.
%
%\begin{definition}[\DescribeMacro{\set}]
%\cs{set}\marg{text}
%\end{definition}
%In addition to the commands provided by \sty{amsmath}, the
%\clsfmt{jmlr} class also provides the \cs{set} command which can
%be used to typeset a set. For example:
%\begin{verbatim}
%The universal set is denoted $\set{U}$
%\end{verbatim}
%
%Unnumbered single-line equations should be displayed using
%\cs{[} and \cs{]}. For example:
%\begin{verbatim}
%\[E = m c^2\]
%\end{verbatim}
%Numbered single-line equations should be displayed using the
%\env{equation} environment. For example:
%\begin{verbatim}
%\begin{equation}\label{eq:trigrule}
%\cos^2\theta + \sin^2\theta \equiv 1
%\end{equation}
%\end{verbatim}
%Multi-lined numbered equations should be displayed using the
%\env{align} environment. For example:
%\begin{verbatim}
%\begin{align}
%f(x) &= x^2 + x\label{eq:f}\\
%f'(x) &= 2x + 1\label{eq:df}
%\end{align}
%\end{verbatim}
%Unnumbered multi-lined equations should be displayed using the
%\env{align*} environment. For example:
%\begin{verbatim}
%\begin{align*}
%f(x) &= (x+1)(x-1)\\
%&= x^2 - 1
%\end{align*}
%\end{verbatim}
%If you want to mix numbered with unnumbered lines use the
%\env{align} environment and suppress unwanted line numbers with
%\cs{nonumber}. For example:
%\begin{verbatim}
%\begin{align}
%y &= x^2 + 3x - 2x + 1\nonumber\\
%&= x^2 + x + 1\label{eq:y}
%\end{align}
%\end{verbatim}
%An equation that is too long to fit on a single line can be
%displayed using the \env{split} environment.
%
%Text can be embedded in an equation using \ics{text}\marg{text} or
%you can use \ics{intertext}\marg{text} to interupt a multi-line
%environment such as \env{align}.
%
%Predefined operator names are listed in \tableref{tab:operatornames}.
%For additional operators, either use
%\begin{definition}[\DescribeMacro{\operatorname}]
%\cs{operatorname}\marg{name}
%\end{definition}
%for example
%\begin{verbatim}
%If $X$ and $Y$ are independent,
%$\operatorname{var}(X+Y) =
%\operatorname{var}(X) + \operatorname{var}(Y)$
%\end{verbatim}
%or declare it with
%\begin{definition}[\DescribeMacro{\DeclareMathOperator}]
%\cs{DeclareMathOperator}\marg{command}\marg{name}
%\end{definition}
%for example
%\begin{verbatim}
%\DeclareMathOperator{\var}{var}
%\end{verbatim}
%and then use this new command:
%\begin{verbatim}
%If $X$ and $Y$ are independent,
%$\var(X+Y) = \var(X)+\var(Y)$
%\end{verbatim}
%
%If you want limits that go above and
%below the operator (like \ics{sum}) use the starred versions
%(\ics{operatorname*} or \ics{DeclareMathOperator*}).

%\subsection{Color vs Grayscale}
%\label{sec:color}
%
%It's helpful if authors supply grayscale versions of their
%articles in the event that the article is to be incorporated into
%a black and white printed book. With external PDF, PNG or JPG
%graphic files, you just need to supply a grayscale version of the
%file. For example, if the file is called \texttt{myimage.png},
%then the gray version should be \texttt{myimage-gray.png} or
%\texttt{myimage-gray.pdf} or \texttt{myimage-gray.jpg}. You don't
%need to modify your code. The \clsfmt{jmlr} class checks for
%the existence of the grayscale version if it is print mode
%(provided you have used \ics{includegraphics} and haven't
%specified the file extension).
%
%\begin{definition}[\DescribeMacro{\ifprint}]
%\cs{ifprint}\marg{true part}\marg{false part}
%\end{definition}
%You can use \cs{ifprint} to determine which mode you are in.
%For example:
%\begin{verbatim}
%in \figureref{fig:nodes}, the
%\ifprint{dark gray}{purple}
%ellipse represents an input and the
%\ifprint{light gray}{yellow} ellipse
%represents an output.
%\end{verbatim}
%Another example:
%\begin{verbatim}
%{\ifprint{\bfseries}{\color{red}}important text!}
%\end{verbatim}
%
%You can use the class option \clsopt{gray} to see how the
%document will appear in gray scale mode.
%
%The \sty{xcolor} class is loaded with the \pkgoptfmt{x11names}
%option, so you can use any of the x11 predefined colors (listed
%in the \ctandoc{xcolor}).
%
%\subsection{Where To Go For Help}
%
%If you have a \LaTeX\ query, the first place to go to is the
%\urlfootref{http://www.tex.ac.uk/faq}{UK TUG FAQ}.
%
%If you are unfamiliar or just getting started with \LaTeX, there's
%a list of on-line introductions to \LaTeX\ at:
%\url{http://www.tex.ac.uk/cgi-bin/texfaq2html?label=man-latex}
%
%There are also forums, mailing lists and newsgroups. For example,
%the \LaTeX\ Community (\url{http://www.latex-community.org/}),
%the \texttt{texhax} mailing list
%(\url{http://tug.org/mailman/listinfo/texhax}) and
%\texttt{comp.text.tex} (archives available at
%\url{http://groups.google.com/group/comp.text.tex/}).
%
%Documentation for packages or classes can be found using the
%\texttt{texdoc} application. For example:
%\begin{verbatim}
%texdoc natbib
%\end{verbatim}
%Alternatively, you can go to
%\texttt{http://www.ctan.org/pkg/}\meta{name} where
%\meta{name} is the name of the package. For example:

%
%\section{Guidelines for Production Editors}
%\label{sec:jmlrbook}
%
%The \clsfmt{jmlrbook} class can be used to combine articles that
%use the \clsfmt{jmlr} document class into a book. The following sample
%files are provided: \texttt{paper1/paper1.tex},
%\texttt{paper2/paper2.tex}, \texttt{paper3/paper3.tex},
%\texttt{jmlr-sample.tex}, \texttt{jmlrwcp-sample.tex} and
%\texttt{jmlrbook-sample.tex}. All but the last named one are
%articles using the \clsfmt{jmlr} class. The last one
%(\texttt{jmlrbook-sample.tex}) uses the \clsfmt{jmlrbook} class file to
%combine the articles into a book. Note that no modifications are
%needed to the files using the \clsfmt{jmlr} class when they are
%imported into the book. They can either be compiled as stand-alone
%articles or with the entire book.
%
%Before you compile the book, make sure that all the articles
%compile as stand-alone documents (and run Bib\TeX\ where
%necessary). You can use the \app{makejmlrbook} Perl script to compile
%the book and create associated HTML files. See
%\sectionref{sec:makejmlrbook} for details.
%
%\subsection{\clsfmt{jmlrbook} Class Options}
%\begin{description}
%\item[\clsopt{nowcp}]The imported pre-published articles were
%published in the Journal of Machine Learning Research (default).
%\item[\clsopt{wcp}] The imported pre-published articles were
%published in the JMLR Workshop and Conference Proceedings.
%
%If the book has a mixture of JMLR and JMLR WCP articles, you
%can switch between them using
%\begin{definition}[\DescribeMacro{\jmlrwcp}]
%\cs{jmlrwcp}
%\end{definition}
%and
%\begin{definition}[\DescribeMacro{\jmlrnowcp}]
%\cs{jmlrnowcp}
%\end{definition}
%Alternatively, you can set the name of the journal or conference
%proceedings using:
%\begin{definition}[\DescribeMacro{\jmlrproceedings}]
%\cs{jmlrproceedings}\marg{short title}\marg{long title}
%\end{definition}
%
%\item[\clsopt{color}] Color version (see \sectionref{sec:color}).
%Use this option for the on-line version with hyperlinks enabled
%(default).
%
%\item[\clsopt{gray}] Grayscale version (see \sectionref{sec:color}).
%Use this option for the print version without hyperlinks.
%
%\item[\clsopt{tablecaptiontop}] in a \env{table} environment,
%\ics{floatconts} puts the caption at the top.
%
%\item[\clsopt{tablecaptionbottom}] in a \env{table} environment,
%\ics{floatconts} puts the caption at the bottom.
%
%\item[\clsopt{letterpaper}] Set the paper size to letter (default).
%
%\item[\clsopt{7x10}] Set the paper size to $7\times10$ inches.
%
%\item[\clsopt{prehyperref}] The \clsfmt{jmlrbook} automatically loads
%the \sty{hyperref} package, but some packages need to be loaded
%before \sty{hyperref}. This information can be specified using
%the \clsopt{prehyperref} option. This is a key=value option. For
%example, to load the packages \styfmt{foo} and \styfmt{bar} before
%\sty{hyperref}, you can do:
%\begin{verbatim}
%\documentclass[prehyperref={\usepackage{foo,bar}}]{jmlrbook}
%\end{verbatim}
%or:
%\begin{verbatim}
%\documentclass[prehyperref={\usepackage{foo}\usepackage{bar}}]{jmlrbook}
%\end{verbatim}
%
%\item[\clsopt{10pt}] Use 10pt as the normal text size.
%\item[\clsopt{11pt}] Use 11pt as the normal text size (default).
%\item[\clsopt{12pt}] Use 12pt as the normal text size.
%
%\end{description}
%
%\subsection{The Preamble}
%
%Any packages that the imported articles load (which aren't
%automatically loaded by \clsfmt{jmlr}) must be loaded in the book's
%preamble. For example, if one or more of the articles load the
%\sty{siunitx} package, this package must be loaded in the book.
%
%Commands that are defined in the imported articles will be local
%to that article unless they have been globally defined using
%\ics{gdef} or \ics{global}. Since most authors use \ics{newcommand}
%and \ics{newenvironment} (or \ics{renewcommand} and
%\ics{renewenvironment}) this shouldn't cause a conflict if more
%that one article has defined the same command or environment.
%For example, in the sample files supplied, both
%\texttt{paper1/paper1.tex} and \texttt{paper2/paper2.tex} have
%defined the command \cs{samplecommand} using \cs{newcommand}. As
%long as this command isn't also defined in the book, there won't
%be a conflict.
%
%\begin{definition}[\DescribeMacro{\title}]
%\cs{title}\oarg{PDF title}\marg{book title}
%\end{definition}
%In the book preamble, \cs{title} sets the book title and the optional
%argument is used for the PDF title, which will be displayed
%when the reader views the PDF file's properties in their PDF viewer.
%(Note that in the imported articles, \cs{title} sets the article's
%title and the optional argument sets the short title for the
%page header and table of contents.)
%
%\begin{definition}[\DescribeMacro{\author}]
%\cs{author}\oarg{PDF author(s)}\marg{book author(s)}
%\end{definition}
%In the book preamble, \cs{author} sets the book's author (or editor)
%and the optional argument is used for the PDF author, which will be
%displayed when the reader views the PDF file's properties in their
%PDF viewer. (Note that in the imported articles, \cs{author} sets
%the article's author and the optional argument sets the short author
%list for the page header.)
%
%\begin{definition}[\DescribeMacro{\volume}]
%\cs{volume}\marg{number}
%\end{definition}
%This command sets the book's volume number. Omit if the book has no
%volume number.
%
%\begin{definition}[\DescribeMacro{\subtitle}]
%\cs{subtitle}\marg{sub-title}
%\end{definition}
%This command sets the book's subtitle. Omit if the book has no
%sub-title.
%
%\begin{definition}[\DescribeMacro{\logo}]
%\cs{logo}\marg{image command}
%\end{definition}
%This sets the book's title image. Use \ics{includegraphics} and
%omit the file extension. If you provide a grayscale version as
%well as a color version, the grayscale version will be used for
%the print version of the book. (See \sectionref{sec:color}
%for further details.)
%
%\begin{definition}[\DescribeMacro{\team}]
%\cs{team}\marg{team title}
%\end{definition}
%This can be used to set the name of the editorial team. This
%command may be omitted if not required.
%
%\begin{definition}[\DescribeMacro{\productioneditor}]
%\cs{productioneditor}\marg{name}
%\end{definition}
%This command may be used to name the production editor. The command
%may be omitted if not required.
%
%See \sectionref{sec:modifytitle} for details on how to modify the
%layout of the title page.
%
%\subsection{Main Book Commands}
%
%All commands that are provided by the \clsfmt{jmlr} class are
%also available with the \clsfmt{jmlrbook} class, but some commands
%might behave differently depending on whether they are in the
%main part of the book or within the imported articles.
%
%In the main part of the book you can use the following commands:
%\begin{definition}[\DescribeMacro{\maketitle}]
%\cs{maketitle}
%\end{definition}
%This displays the book's title page. Note that \cs{maketitle} has
%a different effect when used in imported articles.
%
%\begin{definition}[\DescribeMacro{\frontmatter}]
%\cs{frontmatter}
%\end{definition}
%Use this command at the start of the front matter (e.g.\ before the
%foreword or preface). This will make chapters unnumbered even if you
%use \cs{chapter} instead of \cs{chapter*}. It also sets the page
%style and sets the page numbering to lower case Roman numerals.
%
%\begin{definition}[\DescribeEnv{authorsignoff}]
%\cs{begin}\{authorsignoff\}\\
%\meta{author list}\\
%\cs{end}\{authorsignoff\}
%\end{definition}
%This environment may be used by the author signing off at the end of a chapter such as the
%foreword. Within the environment use:
%\begin{definition}[\DescribeMacro{\Author}]
%\cs{author}\marg{details}
%\end{definition}
%for the author's details. More than one \cs{Author} should be used
%if there is more than one author. Example:
%\begin{verbatim}
%\begin{authorsignoff}
%\Author{Nicola Talbot\\
%University of East Anglia}
%\Author{Anne Author\\
%University of No Where}
%\end{authorsignoff}
%\end{verbatim}
%
%\begin{definition}[\DescribeEnv{signoff}]
%\cs{begin}\{signoff\}\oarg{team name}\marg{date}\\
%\meta{editor list}\\
%\cs{end}\{signoff\}
%\end{definition}
%This environment may be used by the editorial team when signing off
%a chapter such as the preface. If the optional argument is omitted,
%\qt{The Editorial Team} is used.
%
%Within the environment use:
%\begin{definition}[\DescribeMacro{\Editor}]
%\cs{Editor}\marg{details}
%\end{definition}
%for each editor. Example:
%\begin{verbatim}
%\begin{signoff}{March 2010}
%% First editor:
%\Editor{Nicola Talbot\\
%University of East Anglia\\
%\mailto{N.Talbot@uea.ac.uk}}
%% Second editor:
%\Editor{Anne Editor\\
%University of Nowhere\\
%\mailto{ae@sample.com}}
%\end{signoff}
%\end{verbatim}
%
%\begin{definition}[\DescribeMacro{\tableofcontents}]
%\cs{tableofcontents}
%\end{definition}
%This command displays the book's table of contents. Note that it
%has a different effect if used in an imported article.
%
%\begin{definition}[\DescribeMacro{\mainmatter}]
%\cs{mainmatter}
%\end{definition}
%Use this command to switch to the book's main matter. This will
%switch the chapter numbering back on, reset the page numbering to
%Arabic and set up the main page style.
%
%\begin{definition}[\DescribeMacro{\part}]
%\cs{part}\oarg{short title}\marg{title}
%\end{definition}
%If used in the main part of the book, this command will start a
%new part and issue a clear double page. Note that this command
%has a different effect if used in an imported article.
%
%\begin{definition}[\DescribeMacro{\addtocpart}]
%\cs{addtocpart}\marg{title}
%\end{definition}
%This adds \meta{title} to the table of contents, issues a clear
%double page, but doesn't display any text or affect the part
%numbering.
%
%\begin{definition}[\DescribeMacro{\chapter}]
%\cs{chapter}\oarg{short title}\marg{title}
%\end{definition}
%This command may be used in the main body of the book but will
%cause an error if used within an imported article.
%
%\begin{definition}[\DescribeMacro{\section}]
%\cs{section}\oarg{short title}\marg{title}
%\end{definition}
%\begin{definition}[\DescribeMacro{\subsection}]
%\cs{subsection}\oarg{short title}\marg{title}
%\end{definition}
%\begin{definition}[\DescribeMacro{\subsubsection}]
%\cs{subsubsection}\oarg{short title}\marg{title}
%\end{definition}
%\begin{definition}[\DescribeMacro{\paragraph}]
%\cs{paragraph}\oarg{short title}\marg{title}
%\end{definition}
%\begin{definition}[\DescribeMacro{\subparagraph}]
%\cs{subparagraph}\oarg{short title}\marg{title}
%\end{definition}
%These commands may be used in the main body of the book or within
%imported articles. In the main body of the book they need to be
%within a chapter and will be numbered according to the chapter.
%
%\begin{definition}[\DescribeMacro{\appendix}]
%\cs{appendix}
%\end{definition}
%If used in the main body of the book, this will switch to the
%book appendices. Subsequent \cs{chapter} commands will produce the
%appendices. If used within an imported article, it will switch
%to the article appendices and won't affect the main part of
%the book.
%
%\begin{definition}[\DescribeEnv{jmlrpapers}]
%\cs{begin}\{jmlrpapers\}\\
%\meta{imported papers}\\
%\cs{end}\{jmlrpapers\}
%\end{definition}
%This environment must be used when importing articles. Within this
%environment, use the following commands to import articles:
%\begin{definition}[\DescribeMacro{\importpubpaper}]
%\cs{importpubpaper}\oarg{label}\marg{directory}\marg{file}\marg{pages}
%\end{definition}
%This imports an article that has already been published elsewhere.
%The \meta{pages} argument should be the page range from the
%\emph{previously published} version of this article. This may not
%necessarily be the same as the page range of the article in the book.
%The directory the imported file is contained in is is given by
%\meta{directory}. If the file is in the same directory as the
%book, use a dot. The file name is given by \meta{file}. The article
%is also given a label, specified by the optional argument. This
%is \meta{directory}/\meta{file} by default. The label is used
%as a prefix to labels in the imported articles which ensures that
%cross-references are unique. You can also use this label to reference
%the article elsewhere in the book (see \sectionref{sec:bkcrossref}).
%
%\begin{definition}[\DescribeMacro{\importpaper}]
%\cs{importpaper}\oarg{label}\marg{directory}\marg{file}
%\end{definition}
%Imports an article that is being published in the book. The
%arguments are the same as above except that there is no page
%range (the page range is computed automatically).
%
%\begin{definition}[\DescribeMacro{\importarticle}]
%\cs{importarticle}\oarg{label}\marg{directory}\marg{file}
%\end{definition}
%This imports an article that hasn't been published elsewhere. There
%is no page range, but the other arguments are the same as
%those describe above for \cs{importpubpaper}.
%
%Example: to import a previously published paper
%\texttt{paper1/paper1.tex} and an unpublished paper
%\texttt{paper2/paper2.tex}:
%\begin{verbatim}
%\begin{jmlrpapers}
%\importpubpaper{paper1}{paper1}{23--45}
%\importarticle{paper2}{paper2}
%\end{jmlrpapers}
%\end{verbatim}
%
%\subsubsection{Two Column Articles in a One Column Book}
%
%The \clsfmt{jmlrbook} class column style will override the column style
%of the imported articles. You can use the \clsopt{twocolumn} class
%option to \clsfmt{jmlrbook}, but this will make the whole book with
%two columns. If you only want the imported articles to be in two
%columns, then put \ics{twocolumn} in the \env{jmlrpapers}
%environment to switch on two column formatting. The effect will be
%localised to the end of the environment.
%
%\subsubsection{Cross-Referencing}
%\label{sec:bkcrossref}
%
%You can cross-reference other parts of the book using the
%standard \cs{label}/\cs{ref} mechanism, but if you want to
%reference something within an imported article, you must prefix
%the label with the label given when importing the article (that
%is, the optional argument to \ics{importpubpaper},
%\ics{importpaper} or \cs{importarticle}). For example, if you
%want to reference a section labeled \texttt{sec:results} in the
%imported paper \texttt{paper1/paper1.tex}, you would need to do:
%\begin{verbatim}
%see Section~\ref{paper1/paper1sec:results}
%\end{verbatim}
%or
%\begin{verbatim}
%see \sectionref{paper1/paper1sec:results}
%\end{verbatim}
%
%In addition to the commands described in \sectionref{sec:crossref},
%the \clsfmt{jmlrbook} class also provides the following
%cross-referencing commands:
%
%\begin{definition}[\DescribeMacro{\chapterref}]
%\cs{chapterref}\marg{label list}
%\end{definition}
%Reference a chapter or chapters. The argument is a comma-separated
%list of labels.
%
%\begin{definition}[\DescribeMacro{\articlepageref}]
%\cs{articlepageref}\marg{label}
%\end{definition}
%This displays the starting page number of the article whose label
%is given by \meta{label}. Note that this must a single label, not
%a list. For example:
%\begin{verbatim}
%An interesting article starts on page~\articlepageref{paper1/paper1}
%\end{verbatim}
%
%\begin{definition}[\DescribeMacro{\articlepagesref}]
%\cs{articlepagesref}\marg{label}
%\end{definition}
%This displays the page range of the article whose label is
%given by \meta{label}. Again, this must be a single label, not a
%list. This page range is unrelated to the \meta{pages} argument of
%\ics{importpubarticle}.
%
%\begin{definition}[\DescribeMacro{\articletitleref}]
%\cs{articletitleref}\marg{label}
%\end{definition}
%This displays the short title for the article whose label is
%given by \meta{label}. Again, this must be a single label, not a
%list.
%
%\begin{definition}[\DescribeMacro{\articleauthorref}]
%\cs{articleauthorref}\marg{label}
%\end{definition}
%This displays the author list for the article whose label is
%given by \meta{label}. Again, this must be a single label, not a
%list.
%
%\subsection{Altering the Layout of the Main Title Page}
%\label{sec:modifytitle}
%
%\begin{definition}[\DescribeMacro{\titlebody}]
%\cs{titlebody}
%\end{definition}
%The main body of the book's title page is given by the command
%\cs{titlebody}. Within the definition of this command, you can
%use:
%\begin{definition}[\DescribeMacro{\SetTitleElement}]
%\cs{SetTitleElement}\marg{element}\marg{pre}\marg{post}
%\end{definition}
%where \meta{element} can be: \texttt{title}, \texttt{volume},
%\texttt{issue}\footnote{The default title page layout doesn't use
%\texttt{issue}, but if required it can be set with \ics{issue}\marg{number}},
%\texttt{subtitle}, \texttt{logo}, \texttt{team}, \texttt{author},
%\texttt{date}, \texttt{productioneditor}. The \meta{pre} and
%\meta{post} arguments specify what to do before and after the
%element. Note that \cs{SetTitleElement} does nothing if that
%element hasn't been set. For example, if \cs{volume} has been
%omitted or \verb|\volume{}| is used, then
%\begin{verbatim}
%\SetTitleElement{volume}{\mainvolumefont}{\postmainvolume}
%\end{verbatim}
%will do nothing (so you don't end up with \textbf{Volume :}).
%
%\begin{definition}[\DescribeMacro{\IfTitleElement}]
%\cs{IfTitleElement}\marg{element}\marg{true part}\marg{false part}
%\end{definition}
%This does \meta{true part} if \meta{element} has been set
%otherwise it does \meta{false part}. For example,
%\cs{postmainvolume} is defined as:
%\begin{verbatim}
%\newcommand{\postmainvolume}{%
% \IfTitleElement{subtitle}{}{:}\par\relax
%}
%\end{verbatim}
%This means that it will only print a colon after the volume
%number if the subtitle has been set.
%
%The default definition of \cs{titlebody} is:
%\begin{verbatim}

%\subsection{Potential Pitfalls}
%
%The \cls{combine} class and \sty{hyperref} package are
%individually both easily broken by packages that change certain
%internals and they don't ordinarily work together. The
%\clsfmt{jmlrbook} class applies patches to the internal referencing
%mechanism to make them work together, but it's a fairly fragile
%alliance. Some packages are known to break it, for example
%\sty{subfig}, \sty{pdfpages} and \sty{geometry}. This is why the
%\clsfmt{jmlr} class checks for known problem packages and generates an
%error message to dissuade authors from using them. It's likely that
%there are other packages that may cause a problem and, as they are
%found, they will be added to the check list. Also, it's possible for
%an author to disable the package checking mechanism if they are
%determined to use a particular package.
%
%In the event that an article has loaded a problem package, the
%editors will have to decide whether to ask the author to change
%the article so that it doesn't cause a problem or to make the changes
%themselves or to find a way of fudging things to get it to work. It
%depends on the level of \LaTeX\ expertise amongst the editors and
%the time available.
%
%Another problem that can arise is when different articles use
%packages that conflict. For example, one article uses package
%\styfmt{foo} and another uses package \styfmt{bar}. Each article compiles
%okay as a stand-alone article, but when combined \styfmt{foo} and
%\styfmt{bar} conflict. Another problem may occur when articles load the
%same package but with conflicting package options. To reduce the
%chance of this occurring, the \clsfmt{jmlr} class loads some commonly
%used packages. For example, it loads the \sty{algorithm2e}
%package with the \pkgoptfmt{algo2e} and \pkgoptfmt{ruled} options and
%provides the \env{algorithm} environment in addition to
%\sty{algorithm2e}'s \env{algorithm2e} environment.
%
%Articles that use different input encodings can also cause a
%problem. For example, if one article uses \texttt{utf8} and another
%uses \texttt{latin1}. If the authors have directly entered a
%diacritic or ligature, such as \'e or \ae, instead of using a
%\LaTeX\ command, such as \cs{'e} or \cs{ae}, then
%this will cause an error on compiling the book.\footnote{and may also
%cause a problem for the editor's text editor.} The choice then is to
%either change all non-keyboard characters with the appropriate
%\LaTeX\ commands or to use the \cs{inputencoding} command, supplied
%by the \sty{inputenc} package, to switch the encoding at the start
%of each article.
%
%Authors who use \cs{nonumber} within an \env{equation} environment
%can mess up the hyperlinks. Remove \cs{nonumber} and change the
%equation environment to \cs{[} \ldots\ \cs{]} (or just make it a
%numbered equation).
%
%If the article changes the graphics path using \cs{graphicspath},
%\clsfmt{jmlrbook} won't find the graphics if the imported articles
%aren't in the same directory as the book.
%
%\subsection{Creating the Book Using \appfmt{makejmlrbook}}
%\label{sec:makejmlrbook}
%
%The \app{makejmlrbook} Perl script is designed to make it
%easier to produce the print and online versions of the book, as
%well as producing an HTML index of all the imported articles with
%links to the abstracts and PDFs of individual articles. Note that
%for it to work properly, the articles must be imported using
%\cs{importarticle}, \cs{importpaper} or \cs{importpubpaper}, and
%the imported articles must use the \clsfmt{jmlr} class.
%
%On UNIX style systems, the script can be invoked from a terminal
%using:
%\begin{prompt}
%makejmlrbook \oarg{options} \meta{filename}
%\end{prompt}
%If that doesn't work, or you aren't using a UNIX style operating
%system, the script can be invoked from a terminal or command
%prompt using:
%\begin{prompt}
%perl makejmlrbook \oarg{options} \meta{filename}
%\end{prompt}
%The mandatory argument \meta{filename} is the name of the master
%\TeX\ file containing the book. It must use the \clsfmt{jmlrbook}
%class. You may omit the \texttt{.tex} extension. For example, if
%the file is called \texttt{proceedings.tex}, you can call
%\app{makejmlrbook} as follows:
%\begin{verbatim}
%perl makejmlrbook proceedings
%\end{verbatim}
%This will create the files \texttt{proceedings-print.pdf} (the
%print version) and \texttt{proceedings-online.pdf} (the online
%version). It will also create a directory (folder) called
%\texttt{html} in which the HTML files and individual article PDFs
%will be placed.
%
%The options to \app{makejmlrbook} are as follows:
%\begin{description}
%\item[--online] Generate the color on-line version (default).
%\item[--noonline] Don't generate the color on-line version.
%\item[--print] Generate the grayscale print version (default).
%\item[--noprint] Don't generate the grayscale print version.
%\item[--html] Generate the HTML files and the individual article
%PDFs (default).
%\item[--nohtml] Don't generate the HTML files and the individual
%article PDFs.
%\item[--logourl \meta{url}] Make the logo on the HTML index page link
%to \meta{url}.
%\item[--batchtex] Run \TeX\ in batch mode.
%\item[--nobatchtex] Don't run \TeX\ in batch mode (default).
%\item[--quieter] Reduce chatter to STDOUT (doesn't eliminate
%all messages). This also runs \TeX\ in batch mode.
%\item[--noquieter] Don't reduce messages to STDOUT (default).
%\item[--version] Display the version number and exit.
%\item[--help] List all available options.
%\end{description}
%
%There are also some more advanced options, but these haven't been
%fully tested:
%\begin{description}
%\item[--latexapp \meta{name}] Application used to call \LaTeX.
%Defaults to \qt{pdflatex}.
%\item[--latexopt \meta{string}] Options to pass to \LaTeX.
%\item[--format \meta{string}] Output format (defaults to \qt{pdf}).
%This may need to be changed if you change the \LaTeX\ application.
%\item[--bibtexapp \meta{name}] Application use to process the
%bibliography. Defaults to \qt{bibtex}.
%\item[--bibtexopt \meta{string}] Options to pass to Bib\TeX.
