\section{Introduction}
|
|
\label{sec:intro}
|
|
|
|
This is a sample article that uses the \textsf{jmlr} class with
|
|
the \texttt{wcp} class option. Please follow the guidelines in
|
|
this sample document as it can help to reduce complications when
|
|
combining the articles into a book. Please avoid using obsolete
|
|
commands, such as \verb|\rm|, and obsolete packages, such as
|
|
\textsf{epsfig}.\footnote{See
|
|
\url{http://www.ctan.org/pkg/l2tabu}}
|
|
|
|
Please also ensure that your document will compile with PDF\LaTeX.
|
|
If you have an error message that's puzzling you, first check for it
|
|
at the UK TUG FAQ
|
|
\url{http://www.tex.ac.uk/cgi-bin/texfaq2html?label=man-latex}. If
|
|
that doesn't help, create a minimal working example (see
|
|
\url{http://theoval.cmp.uea.ac.uk/~nlct/latex/minexample/}) and post
|
|
to somewhere like TeX on StackExchange
|
|
(\url{http://tex.stackexchange.com/}) or the LaTeX Community Forum
|
|
(\url{http://www.latex-community.org/forum/}).
|
|
|

|
|
|
|
Sub-sub-sections are produced using \verb|\subsubsection|.
|
|
|
|
\paragraph{Sub-sub-sub-sections}
|
|
|
|

|
|
|
|
\section{Cross-Referencing}
|
|
|
|
Always use \verb|\label| and \verb|\ref| (or one of the commands
|
|
described below) when cross-referencing. For example, the next
|
|
section is Section~\ref{sec:math}. The \textsf{jmlr} class
|
|
provides some convenient cross-referencing commands:
|
|
\verb|\sectionref|, \verb|\equationref|, \verb|\tableref|,
|
|
\verb|\figureref|, \verb|\algorithmref|, \verb|\theoremref|,
|
|
\verb|\lemmaref|, \verb|\remarkref|, \verb|\corollaryref|,
|
|
\verb|\definitionref|, \verb|\conjectureref|, \verb|\axiomref|,
|
|
\verb|\exampleref| and \verb|\appendixref|. The argument of these
|
|
commands may either be a single label or a comma-separated list
|
|
of labels. Examples:
|
|
|
|
Referencing sections: \sectionref{sec:math} or
|
|
\sectionref{sec:intro,sec:math} or
|
|
\sectionref{sec:intro,sec:math,sec:tables,sec:figures}.
|
|
|
|
Referencing equations: \equationref{eq:trigrule} or
|
|
\equationref{eq:trigrule,eq:df} or
|
|
\equationref{eq:trigrule,eq:f,eq:df,eq:y}.
|
|
|
|
Referencing tables: \tableref{tab:operatornames} or
|
|
\tableref{tab:operatornames,tab:example} or
|
|
\tableref{tab:operatornames,tab:example,tab:example-booktabs}.
|
|
|
|
Referencing figures: \figureref{fig:nodes} or
|
|
\figureref{fig:nodes,fig:teximage} or
|
|
\figureref{fig:nodes,fig:teximage,fig:subfigex} or
|
|
\figureref{fig:circle,fig:square}.
|
|
|
|
Referencing algorithms: \algorithmref{alg:gauss} or
|
|
\algorithmref{alg:gauss,alg:moore} or
|
|
\algorithmref{alg:gauss,alg:moore,alg:net}.
|
|
|
|
Referencing theorem-like environments: \theoremref{thm:eigenpow},
|
|
\lemmaref{lem:sample}, \remarkref{rem:sample},
|
|
\corollaryref{cor:sample}, \definitionref{def:sample},
|
|
\conjectureref{con:sample}, \axiomref{ax:sample} and
|
|
\exampleref{ex:sample}.
|
|
|
|
Referencing appendices: \appendixref{apd:first} or
|
|
\appendixref{apd:first,apd:second}.
|
|
|
|
\section{Equations}
|
|
\label{sec:math}
|
|
|
|
The \textsf{jmlr} class loads the \textsf{amsmath} package, so
|
|
you can use any of the commands and environments defined there.
|
|
(See the \textsf{amsmath} documentation for further
|
|
details.\footnote{Either \texttt{texdoc amsmath} or
|
|
\url{http://www.ctan.org/pkg/amsmath}})
|
|
|
|
Unnumbered single-lined equations should be displayed using
|
|
\verb|\[| and \verb|\]|. For example:
|
|
\[E = m c^2\]
|
|
Numbered single-line equations should be displayed using the
|
|
\texttt{equation} environment. For example:
|
|
\begin{equation}\label{eq:trigrule}
|
|
\cos^2\theta + \sin^2\theta \equiv 1
|
|
\end{equation}
|
|
This can be referenced using \verb|\label| and \verb|\equationref|.
|
|
For example, \equationref{eq:trigrule}.
|
|
|
|
Multi-lined numbered equations should be displayed using the
|
|
\texttt{align} environment.\footnote{For reasons why you
|
|
shouldn't use the obsolete \texttt{eqnarray} environment, see
|
|
Lars Madsen, \emph{Avoid eqnarray!} TUGboat 33(1):21--25, 2012.} For example:
|
|
\begin{align}
|
|
f(x) &= x^2 + x\label{eq:f}\\
|
|
f'(x) &= 2x + 1\label{eq:df}
|
|
\end{align}
|
|
Unnumbered multi-lined equations should be displayed using the
|
|
\texttt{align*} environment. For example:
|
|
\begin{align*}
|
|
f(x) &= (x+1)(x-1)\\
|
|
&= x^2 - 1
|
|
\end{align*}
|
|
If you want to mix numbered with unnumbered lines use the
|
|
align environment and suppress unwanted line numbers with
|
|
\verb|\nonumber|. For example:
|
|
\begin{align}
|
|
y &= x^2 + 3x - 2x + 1\nonumber\\
|
|
&= x^2 + x + 1\label{eq:y}
|
|
\end{align}
|
|
An equation that is too long to fit on a single line can be
|
|
displayed using the \texttt{split} environment.
|
|
Text can be embedded in an equation using \verb|\text| or
|
|
\verb|\intertext| (as used in \theoremref{thm:eigenpow}).
|
|
See the \textsf{amsmath} documentation for further details.
|
|
|
|
\subsection{Operator Names}
|
|
\label{sec:op}
|
|
|
|
Predefined operator names are listed in \tableref{tab:operatornames}.
|
|
For additional operators, either use \verb|\operatorname|,
|
|
for example $\operatorname{var}(X)$ or declare it with
|
|
\verb|\DeclareMathOperator|, for example
|
|
\begin{verbatim}
|
|
\DeclareMathOperator{\var}{var}
|
|
\end{verbatim}
|
|
and then use this new command. If you want limits that go above and
|
|
below the operator (like \verb|\sum|) use the starred versions
|
|
(\verb|\operatorname*| or \verb|\DeclareMathOperator*|).
|
|
|

}
|
|
\end{table}
|
|
|
|
\section{Vectors and Sets}
|
|
\label{sec:vec}
|
|
|
|
Vectors should be typeset using \cs{vec}. For example $\vec{x}$.
|
|
The \textsf{jmlr} class also provides \cs{set} to typeset a
|
|
set. For example $\set{S}$.
|
|
|
|
\section{Floats}
|
|
\label{sec:floats}
|
|
|
|
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 figure or table 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
|
|
spacing 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}
|
|
|
|
\subsection{Tables}
|
|
\label{sec:tables}
|
|
|
|
Tables should go in the \texttt{table} environment. Within this
|
|
environment use \verb|\floatconts| (defined by \textsf{jmlr})
|
|
to set the caption correctly and center the table contents.
|
|
|
|
\begin{table}[htbp]
|
|
% The first argument is the label.
|
|
% The caption goes in the second argument, and the table contents
|
|
% go in the third argument.
|
|
\floatconts
|
|
{tab:example}%
|
|
{\caption{An Example Table}}%
|
|
{\begin{tabular}{ll}
|
|
\bfseries Dataset & \bfseries Result\\
|
|
Data1 & 0.12345\\
|
|
Data2 & 0.67890\\
|
|
Data3 & 0.54321\\
|
|
Data4 & 0.09876
|
|
\end{tabular}}
|
|
\end{table}
|
|
|
|
If you want horizontal rules you can use the \textsf{booktabs}
|
|
package which provides the commands \verb|\toprule|,
|
|
\verb|\midrule| and \verb|\bottomrule|. For example, see
|
|
\tableref{tab:example-booktabs}.
|
|
|
|
\begin{table}[hbtp]
|
|
\floatconts
|
|
{tab:example-booktabs}
|
|
{\caption{A Table With Horizontal Lines}}
|
|
{\begin{tabular}{ll}
|
|
\toprule
|
|
\bfseries Dataset & \bfseries Result\\
|
|
\midrule
|
|
Data1 & 0.12345\\
|
|
Data2 & 0.67890\\
|
|
Data3 & 0.54321\\
|
|
Data4 & 0.09876\\
|
|
\bottomrule
|
|
\end{tabular}}
|
|
\end{table}
|
|
|
|
If you want vertical lines as well, you can't use the
|
|
\textsf{booktabs} commands as there'll be some unwanted gaps.
|
|
Instead you can use \LaTeX's \verb|\hline|, but the rows may
|
|
appear a bit cramped. You can add extra space above or below a
|
|
row using \verb|\abovestrut| and \verb|\belowstrut|. For example,
|
|
see \tableref{tab:example-hline}.
|
|
|
|
\begin{table}[htbp]
|
|
\floatconts
|
|
{tab:example-hline}
|
|
{\caption{A Table With Horizontal and Vertical Lines}}%
|
|
{%
|
|
\begin{tabular}{|l|l|}
|
|
\hline
|
|
\abovestrut{2.2ex}\bfseries Dataset & \bfseries Result\\\hline
|
|
\abovestrut{2.2ex}Data1 & 0.12345\\
|
|
Data2 & 0.67890\\
|
|
Data3 & 0.54321\\
|
|
\belowstrut{0.2ex}Data4 & 0.09876\\\hline
|
|
\end{tabular}
|
|
}
|
|
\end{table}
|
|
|
|
If you want to align numbers on their decimal point, you can
|
|
use the \textsf{siunitx} package. For example, see
|
|
\tableref{tab:example-siunitx}. For further details see the
|
|
\textsf{siunitx} documentation\footnote{Either \texttt{texdoc
|
|
siunitx} or \url{http://www.ctan.org/pkg/siunitx}}.
|
|
|
|
\begin{table}[htbp]
|
|
\floatconts
|
|
{tab:example-siunitx}
|
|
{\caption{A Table With Numbers Aligned on the Decimal Point}}
|
|
{\begin{tabular}{lS[tabformat=3.5]}
|
|
\bfseries Dataset & {\bfseries Result}\\
|
|
Data1 & 0.12345\\
|
|
Data2 & 10.6789\\
|
|
Data3 & 50.543\\
|
|
Data4 & 200.09876
|
|
\end{tabular}}
|
|
\end{table}
|
|
|
|
If the table is too wide, you can adjust the inter-column
|
|
spacing by changing the value of \verb|\tabcolsep|. For
|
|
example:
|
|
\begin{verbatim}
|
|
\setlength{\tabcolsep}{3pt}
|
|
\end{verbatim}
|
|
If the table is very wide but not very long, you can use the
|
|
\texttt{sidewaystable} environment defined in the
|
|
\textsf{rotating} package (so use \verb|\usepackage{rotating}|).
|
|
If the table is too long to fit on a page, you should use the
|
|
\texttt{longtable} environment defined in the \textsf{longtable}
|
|
package (so use \verb|\usepackage{longtable}|).
|
|
|
|
\subsection{Figures}
|
|
\label{sec:figures}
|
|
|
|
Figures should go in the \texttt{figure} environment. Within this
|
|
environment, use \verb|\floatconts| to correctly position the
|
|
caption and center the image. Use \verb|\includegraphics|
|
|
for external graphics files but omit the file extension. Do not
|
|
use \verb|\epsfig| or \verb|\psfig|. If you want to scale the
|
|
image, it's better to use a fraction of the line width rather
|
|
than an explicit length. For example, see \figureref{fig:nodes}.
|
|
|
|
\begin{figure}[htbp]
|
|
% Caption and label go in the first argument and the figure contents
|
|
% go in the second argument
|
|
\floatconts
|
|
{fig:nodes}
|
|
{\caption{Example Image}}
|
|
{\includegraphics[width=0.5\linewidth]{images/nodes}}
|
|
\end{figure}
|
|
|
|
If your image is made up of \LaTeX\ code (for example, commands
|
|
provided by the \textsf{pgf} package) you can include it using
|
|
\cs{includeteximage} (defined by the \textsf{jmlr} class). This
|
|
can be scaled and rotated in the same way as \cs{includegraphics}.
|
|
For example, see \figureref{fig:teximage}.
|
|
|
|
\begin{figure}[htbp]
|
|
\floatconts
|
|
{fig:teximage}
|
|
{\caption{Image Created Using \LaTeX\ Code}}
|
|
{\includeteximage[angle=45]{images/teximage}}
|
|
\end{figure}
|
|
|
|
If the figure is too wide to fit on the page, you can use the
|
|
\texttt{sidewaysfigure} environment defined in the
|
|
\textsf{rotating} package.
|
|
|
|
Don't use \verb|\graphicspath|. If the images are contained in
|
|
a subdirectory, specify this when you include the image, for
|
|
example \verb|\includegraphics{figures/mypic}|.
|
|
|
|
\subsubsection{Sub-Figures}
|
|
\label{sec:subfigures}
|
|
|
|
Sub-figures can be created using \verb|\subfigure|, which is
|
|
defined by the \textsf{jmlr} class. The optional argument allows
|
|
you to provide a subcaption. The label should be placed in the
|
|
mandatory argument of \verb|\subfigure|. You can reference the
|
|
entire figure, for example \figureref{fig:subfigex}, or you can
|
|
reference part of the figure using \verb|\figureref|, for example
|
|
\figureref{fig:circle}. Alternatively you can reference the
|
|
subfigure using \verb|\subfigref|, for example
|
|
\subfigref{fig:circle,fig:square} in \figureref{fig:subfigex}.
|
|
|
|
\begin{figure}[htbp]
|
|
\floatconts
|
|
{fig:subfigex}
|
|
{\caption{An Example With Sub-Figures.}}
|
|
{%
|
|
\subfigure[A Circle]{\label{fig:circle}%
|
|
\includegraphics[width=0.2\linewidth]{images/circle}}%
|
|
\qquad
|
|
\subfigure[A Square]{\label{fig:square}%
|
|
\includegraphics[width=0.2\linewidth]{images/square}}
|
|
}
|
|
\end{figure}
|
|
|
|
By default, the sub-figures are aligned on the baseline.
|
|
This can be changed using the second optional argument
|
|
of \verb|\subfigure|. This may be \texttt{t} (top), \texttt{c}
|
|
(centered) or \texttt{b} (bottom). For example, the subfigures
|
|
\subfigref{fig:circle2,fig:square2} in \figureref{fig:subfigex2}
|
|
both have \verb|[c]| as the second optional argument.

\subsection{Sub-Tables}
|
|
\label{sec:subtables}
|
|
There is an analogous command \verb|\subtable| for sub-tables.
|
|
It has the same syntax as \verb|\subfigure| described above.
|
|
You can reference the table using \verb|\tableref|, for example
|
|
\tableref{tab:subtabex} or you can reference part of the table,
|
|
for example \tableref{tab:ab}. Alternatively you can reference the
|
|
subtable using \verb|\subtabref|, for example
|
|
\subtabref{tab:ab,tab:cd} in \tableref{tab:subtabex}.
|
|
|
|
\begin{table}[htbp]
|
|
\floatconts
|
|
{tab:subtabex}
|
|
{\caption{An Example With Sub-Tables}}
|
|
{%
|
|
\subtable{%
|
|
\label{tab:ab}%
|
|
\begin{tabular}{cc}
|
|
\bfseries A & \bfseries B\\
|
|
1 & 2
|
|
\end{tabular}
|
|
}\qquad
|
|
\subtable{%
|
|
\label{tab:cd}%
|
|
\begin{tabular}{cc}
|
|
\bfseries C & \bfseries D\\
|
|
3 & 4\\
|
|
5 & 6
|
|
\end{tabular}
|
|
}
|
|
}
|
|
\end{table}
|
|
|
|
By default, the sub-tables are aligned on the top.
|
|
This can be changed using the second optional argument
|
|
of \verb|\subtable|. This may be \texttt{t} (top), \texttt{c}
|
|
(centered) or \texttt{b} (bottom). For example, the sub-tables
|
|
\subtabref{tab:ab2,tab:cd2} in \tableref{tab:subtabex2}
|
|
both have \verb|[c]| as the second optional argument.
|
|
|
|
\begin{table}[htbp]
|
|
\floatconts
|
|
{tab:subtabex2}
|
|
{\caption{Another Example With Sub-Tables}}
|

|
|
\begin{tabular}{cc}

|
|

|
|
\end{tabular}
|
|
}\qquad
|
|
\subtable[][c]{%
|
|
\label{tab:cd2}%
|
|
\begin{tabular}{cc}

|
|
3 & 4\\
|
|
5 & 6
|
|
\end{tabular}
|
|
}
|
|
}
|
|
\end{table}
|
|

|
\subsection{Algorithms}
|
|
\label{sec:algorithms}
|
|
|
|
Enumerated textual algorithms can be displayed using the
|
|
\texttt{algorithm} environment. Within this environment, use
|
|
use an \texttt{enumerate} or nested \texttt{enumerate} environments.
|
|
For example, see \algorithmref{alg:gauss}. Note that algorithms
|
|
float like figures and tables.
|
|
|
|
\begin{algorithm}[htbp]
|
|
\floatconts
|
|
{alg:gauss}% label
|
|
{\caption{The Gauss-Seidel Algorithm}}
|
|
{% contents
|
|
\begin{enumerate}
|
|
\item For $k=1$ to maximum number of iterations
|
|
\begin{enumerate}
|
|
\item For $i=1$ to $n$
|
|
\begin{enumerate}
|
|
\item $x_i^{(k)} =
|
|
\frac{b_i - \sum_{j=1}^{i-1}a_{ij}x_j^{(k)}
|
|
- \sum_{j=i+1}^{n}a_{ij}x_j^{(k-1)}}{a_{ii}}$
|
|
\item If $\|\vec{x}^{(k)}-\vec{x}^{(k-1)} < \epsilon\|$,
|
|
where $\epsilon$ is a specified stopping criteria, stop.
|
|
\end{enumerate}
|
|
\end{enumerate}
|
|
\end{enumerate}
|
|
}
|
|
\end{algorithm}
|
|
|
|
You can use \verb|\caption| and \verb|\label| without using
|
|
\verb|\floatconts| (as in \algorithmref{alg:moore}).
|
|
|
|
If you'd rather have the same numbering throughout the algorithm
|
|
but still want the convenient indentation of nested
|
|
\texttt{enumerate} environments, you can use the
|
|
\texttt{enumerate*} environment provided by the \textsf{jmlr}
|
|
class. For example, see \algorithmref{alg:moore}.
|
|
|
|
\begin{algorithm}
|
|
\caption{Moore's Shortest Path}\label{alg:moore}
|
|
Given a connected graph $G$, where the length of each edge is 1:
|
|
\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}
|
|
|
|
Pseudo code can be displayed using the \texttt{algorithm2e}
|
|
environment. This is defined by the \textsf{algorithm2e} package
|
|
(which is automatically loaded) so check the \textsf{algorithm2e}
|
|
documentation for further details.\footnote{Either \texttt{texdoc
|
|
algorithm2e} or \url{http://www.ctan.org/pkg/algorithm2e}}
|
|
For an example, see \algorithmref{alg:net}.
|
|
|
|
\begin{algorithm2e}
|
|
\caption{Computing Net Activation}
|
|
\label{alg:net}
|
|
% older versions of algorithm2e have \dontprintsemicolon instead
|
|

\For{$i\leftarrow 1$ \KwTo $n$}{
|
|
$y \leftarrow y + w_i*x_i$\;
|
|
}
|
|
\end{algorithm2e}
|
|
|
|
\section{Description Lists}
|
|
|
|
The \textsf{jmlr} class also provides a description-like
|
|
environment called \texttt{altdescription}. This has an
|
|
argument that should be the widest label in the list. Compare:
|
|
\begin{description}
|
|
\item[add] A method that adds two variables.
|
|
\item[differentiate] A method that differentiates a function.
|
|
\end{description}
|
|
with
|
|
\begin{altdescription}{differentiate}
|
|
\item[add] A method that adds two variables.
|
|
\item[differentiate] A method that differentiates a function.
|
|
\end{altdescription}
|
|
|
|
\section{Theorems, Lemmas etc}
|
|
\label{sec:theorems}
|
|
|
|
The following theorem-like environments are predefined by
|
|
the \textsf{jmlr} class: \texttt{theorem}, \texttt{example},
|
|
\texttt{lemma}, \texttt{proposition}, \texttt{remark},
|
|
\texttt{corollary}, \texttt{definition}, \texttt{conjecture}
|
|
and \texttt{axiom}. You can use the \texttt{proof} environment
|
|
to display the proof if need be, as in \theoremref{thm:eigenpow}.
|
|
|
|
\begin{theorem}[Eigenvalue Powers]\label{thm:eigenpow}
|
|
If $\lambda$ is an eigenvalue of $\vec{B}$ with eigenvector
|
|
$\vec{\xi}$, then $\lambda^n$ is an eigenvalue of $\vec{B}^n$
|
|
with eigenvector $\vec{\xi}$.
|
|
\begin{proof}
|
|
Let $\lambda$ be an eigenvalue of $\vec{B}$ with eigenvector
|
|
$\xi$, then
|
|
\begin{align*}
|
|
\vec{B}\vec{\xi} &= \lambda\vec{\xi}
|
|
\intertext{premultiply by $\vec{B}$:}
|
|
\vec{B}\vec{B}\vec{\xi} &= \vec{B}\lambda\vec{\xi}\\
|
|
\Rightarrow \vec{B}^2\vec{\xi} &= \lambda\vec{B}\vec{\xi}\\
|
|
&= \lambda\lambda\vec{\xi}\qquad
|
|
\text{since }\vec{B}\vec{\xi}=\lambda\vec{\xi}\\
|
|
&= \lambda^2\vec{\xi}
|
|
\end{align*}
|
|
Therefore true for $n=2$. Now assume true for $n=k$:
|
|
\begin{align*}
|
|
\vec{B}^k\vec{\xi} &= \lambda^k\vec{\xi}
|
|
\intertext{premultiply by $\vec{B}$:}
|
|
\vec{B}\vec{B}^k\vec{\xi} &= \vec{B}\lambda^k\vec{\xi}\\
|
|
\Rightarrow \vec{B}^{k+1}\vec{\xi} &= \lambda^k\vec{B}\vec{\xi}\\
|
|
&= \lambda^k\lambda\vec{\xi}\qquad
|
|
\text{since }\vec{B}\vec{\xi}=\lambda\vec{\xi}\\
|
|
&= \lambda^{k+1}\vec{\xi}
|
|
\end{align*}
|
|
Therefore true for $n=k+1$. Therefore, by induction, true for all
|
|
$n$.
|
|
\end{proof}
|
|
\end{theorem}

\section{Color vs Grayscale}
|
|
\label{sec:color}
|
|
|
|
It's helpful if authors supply grayscale versions of their
|
|
images 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 \textsf{jmlr} class checks for
|
|
the existence of the grayscale version if it is print mode
|
|
(provided you have used \verb|\includegraphics| and haven't
|
|
specified the file extension).
|
|
|
|
You can use \verb|\ifprint| to determine which mode you are in.
|
|
For example, in \figureref{fig:nodes}, the
|
|
\ifprint{dark gray}{purple} ellipse represents an input and the
|
|
\ifprint{light gray}{yellow} ellipse represents an output.
|
|
Another example: {\ifprint{\bfseries}{\color{red}}important text!}
|
|
|
|
You can use the class option \texttt{gray} to see how the
|
|
document will appear in gray scale mode. \textcolor{blue}{Colored
|
|
text} will automatically be converted to gray scale.
|
|
|
|
The \textsf{jmlr} class loads the \textsf{xcolor}
|
|
package, so you can also define your own colors. For example:
|
|
\ifprint
|
|
{\definecolor{myred}{gray}{0.5}}%
|
|
{\definecolor{myred}{rgb}{0.5,0,0}}%
|
|
\textcolor{myred}{XYZ}.
|
|
|
|
The \textsf{xcolor} class is loaded with the \texttt{x11names}
|
|
option, so you can use any of the x11 predefined colors (listed
|
|
in the \textsf{xcolor} documentation\footnote{either
|
|
\texttt{texdoc xcolor} or \url{http://www.ctan.org/pkg/xcolor}}).
|
|
|
|
\section{Citations and Bibliography}
|
|
\label{sec:cite}
|
|
|
|
The \textsf{jmlr} class automatically loads \textsf{natbib}.
|
|
This sample file has the citations defined in the accompanying
|
|
BibTeX file \texttt{jmlr-sample.bib}. For a parenthetical
|
|
citation use \verb|\citep|. For example
|
|
\citep{guyon-elisseeff-03}. For a textual citation use
|
|
\verb|\citet|. For example \citet{guyon2007causalreport}.
|
|
Both commands may take a comma-separated list, for example
|
|
\citet{guyon-elisseeff-03,guyon2007causalreport}.
|
|
|
|
These commands have optional arguments and have a starred
|
|
version. See the \textsf{natbib} documentation for further
|
|
details.\footnote{Either \texttt{texdoc natbib} or
|
|
\url{http://www.ctan.org/pkg/natbib}}
|
|
|
|
The bibliography is displayed using \verb|\bibliography|.
