= Submission of conference papers to ICLR 2025

ICLR requires electronic submissions, processed by
#url("https://openreview.net/"). See ICLR's website for more instructions.

If your paper is ultimately accepted, the statement `\iclrfinalcopy` should be
inserted to adjust the format to the camera ready requirements.

The format for the submissions is a variant of the NeurIPS format. Please read
carefully the instructions below, and follow them faithfully.

== Style

Papers to be submitted to ICLR 2025 must be prepared according to the
instructions presented here.

Authors are required to use the ICLR #LaTeX style files obtainable at the ICLR
website. Please make sure you use the current files and not previous versions.
Tweaking the style files may be grounds for rejection.

== Retrieval of style files

The style files for ICLR and other conference information are available online
at:

#block(width: 100%, spacing: 13.5pt, {
  set align(center)
  url("https://www.iclr.cc/")
})

The file `iclr2025_conference.pdf` contains these instructions and illustrates
the various formatting requirements your ICLR paper must satisfy. Submissions
must be made using #LaTeX and the style files `iclr2025_conference.sty` and
`iclr2025_conference.bst` (to be used with #LaTeXe). The file
`iclr2025_conference.tex` may be used as a "shell" for writing your paper. All
you have to do is replace the author, title, abstract, and text of the paper
with your own.

The formatting instructions contained in these style files are summarized in
sections #ref(<gen_inst>, supplement: none), #ref(<headings>, supplement:
none), and #ref(<others>, supplement: none) below.

#v(-3pt)  // Reduce spacing manually because of LaTeX/LaTeXe ligatures.

= General formatting instructions <gen_inst>

The text must be confined within a rectangle 5.5~inches (33~picas) wide and
9~inches (54~picas) long. The left margin is 1.5~inch (9~picas). Use 10~point
type with a vertical spacing of 11~points. Times New Roman is the preferred
typeface throughout. Paragraphs are separated by 1/2~line space, with no
indentation.

Paper title is 17~point, in small caps and left-aligned. All pages should start
at 1~inch (6~picas) from the top of the page.

Authors' names are set in boldface, and each name is placed above its
corresponding address. The lead author's name is to be listed first, and the
co-authors' names are set to follow. Authors sharing the same address can be on
the same line.

Please pay special attention to the instructions in @others regarding figures,
tables, acknowledgments, and references.

There will be a strict upper limit of 10 pages for the main text of the initial
submission, with unlimited additional pages for citations.

= Headings: first level <headings>

First level headings are in small caps, flush left and in point size 12. One
line space before the first level heading and 1/2~line space after the first
level heading.

== Headings: second level

Second level headings are in small caps, flush left and in point size 10. One
line space before the second level heading and 1/2~line space after the second
level heading.

=== Headings: third level

Third level headings are in small caps, flush left and in point size 10. One
line space before the third level heading and 1/2~line space after the third
level heading.

= Citations, figures, tables, references <others>

These instructions apply to everyone, regardless of the formatter being used.

== Citations within the text

Citations within the text should be based on the `natbib` package and include
the authors' last names and year (with the "et~al." construct for more than two
authors). When the authors or the publication are included in the sentence, the
citation should not be in parenthesis using `\citet{}` (as in "See
#cite(<Hinton06>, form: "prose") for more information."). Otherwise, the
citation should be in parenthesis using `\citep{}` (as in "Deep learning shows
promise to make progress towards AI~@Bengio_chapter2007.").

The corresponding references are to be listed in alphabetical order of authors,
in the #smallcaps[References] section. As to the format of the references
themselves, any style is acceptable as long as it is used consistently.

== Footnotes

Indicate footnotes with a number#footnote[Sample of the first footnote] in the
text. Place the footnotes at the bottom of the page on which they appear.
Precede the footnote with a horizontal rule of 2~inches
(12~picas).#footnote[Sample of the second footnote]

== Figures

All artwork must be neat, clean, and legible. Lines should be dark enough for
purposes of reproduction; art work should not be hand-drawn. The figure number
and caption always appear after the figure. Place one line space before the
figure caption, and one line space after the figure. The figure caption is
lower case (except for first word and proper nouns); figures are numbered
consecutively.

Make sure the figure caption does not get separated from the figure. Leave
sufficient space to avoid splitting the figure and figure caption.

You may use color figures. However, it is best for the figure captions and the
paper body to make sense if the paper is printed either in black/white or in
color.

#figure(
  caption: [Sample figure caption.],
  rect(width: 4.25cm, height: 4.25cm, stroke: 0.4pt),
)

== Tables

All tables must be centered, neat, clean and legible. Do not use hand-drawn
tables. The table number and title always appear before the table. See
@sample-table.

Place one line space before the table title, one line space after the table
title, and one line space after the table. The table title must be lower case
(except for first word and proper nouns); tables are numbered consecutively.

#figure(
  caption: [Sample table title],
  placement: top,
  table(
    columns: 2,
    stroke: none,
    table.header([*NAME*], [*DESCRIPTION*]),
    table.hline(),
    [Dendrite], [Input terminal ],
    [Axon    ], [Output terminal],
    [Soma    ], [Cell body (contains cell nucleus)],
  )
) <sample-table>

= Default Notation

In an attempt to encourage standardized notation, we have included the notation
file from the textbook, _Deep Learning_ @goodfellow2016deep available at
#url("https://github.com/goodfeli/dlbook_notation/").  Use of this style is not
required and can be disabled by commenting out `math_commands.tex`.

= Final instructions

Do not change any aspects of the formatting parameters in the style files. In
particular, do not modify the width or length of the rectangle the text should
fit into, and do not change font sizes (except perhaps in the
#smallcaps[References] section; see below). Please note that pages should be
numbered.

= Preparing PostScript or PDF files

Please prepare PostScript or PDF files with paper size "US Letter", and not,
for example, "A4". The `-t` letter option on dvips will produce US Letter
files.

Consider directly generating PDF files using `pdflatex` (especially if you are
a MiKTeX user). PDF figures must be substituted for EPS figures, however.

Otherwise, please generate your PostScript and PDF files with the following
commands:

```shell
  dvips mypaper.dvi -t letter -Ppdf -G0 -o mypaper.ps
  ps2pdf mypaper.ps mypaper.pdf
```

== Margins in #LaTeX

Most of the margin problems come from figures positioned by hand using
`\special` or other commands. We suggest using the command `\includegraphics`
from the graphicx package. Always specify the figure width as a multiple of the
line width as in the example below using .eps graphics
```tex
   \usepackage[dvips]{graphicx} ...
   \includegraphics[width=0.8\linewidth]{myfile.eps}
```
or
```tex
   \usepackage[pdftex]{graphicx} ...
   \includegraphics[width=0.8\linewidth]{myfile.pdf}
```
for .pdf graphics. See Section~4.4 in the graphics bundle documentation
(#url("http://www.ctan.org/tex-archive/macros/latex/required/graphics/grfguide.ps").

A number of width problems arise when #LaTeX cannot properly hyphenate a line.
Please give #LaTeX hyphenation hints using the `\-` command.

== Author Contributions

If you'd like to, you may include  a section for author contributions as is
done in many journals. This is optional and at the discretion of the authors.

=== Acknowledgments

Use unnumbered third level headings for the acknowledgments. All
acknowledgments, including those to funding agencies, go at the end of the
paper.
