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 NIPS format. Please read carefully the instructions below, and follow them faithfully.

1.1. STYLE:

Papers to be submitted to ICLR 2019 must be prepared according to the instructions presented here.

Authors are required to use the ICLR L A T E X 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.

1.2. RETRIEVAL OF STYLE FILES:

The style files for ICLR and other conference information are available on the World Wide Web at http://www.iclr.cc/ The file iclr2019_conference.pdf contains these instructions and illustrates the various formatting requirements your ICLR paper must satisfy. Submissions must be made using L A T E X and the style files iclr2019_conference.sty and iclr2019_conference.bst (to be used with L A T E X2e). The file iclr2019_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 2, 3, and 4 below.

2. GENERAL FORMATTING INSTRUCTIONS:

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. 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 section 4 regarding figures, tables, acknowledgments, and references.

3 HEADINGS: FIRST LEVEL 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.

3.1. 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.

3.1.1. 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.

4. CITATIONS, FIGURES, TABLES, REFERENCES:

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

4.1. 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 (as in "See Hinton et al. (2006) for more information."). Otherwise, the citation should be in parenthesis (as in "Deep learning shows promise to make progress towards AI (Bengio & LeCun, 2007) .").

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

4.2. FOOTNOTES:

Indicate footnotes with a number1 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). 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. 

∂f ∂x Jacobian matrix J ∈ R m×n of f : R n → R m ∇ 2 x f (x) or H(f )(x)

The Hessian matrix of f at input point x 

f (x)dx Definite integral

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.

Figures and Tables:

2

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.

over the entire domain of x 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 REFERENCES section; see below). Please note that pages should be numbered.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 \usepackage[dvips]{graphicx} ... \includegraphics[width=0.8\linewidth]{myfile.eps} or \usepackage[pdftex]{graphicx} ... \includegraphics[width=0.8\linewidth]{myfile.pdf} for .pdf graphics. See section 4.4 in the graphics bundle documentation (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.

Peer review (iclr2019):
 Authors present a new LSTM architecture, i.e. reduced gate convolutional LSTM. Authors use only one trainable gate, i.e. the forget gate which leads to less trainable parameters. They demonstrate the superiority of ti in two datasets, the moving MNIST and KITTI. Their results show that their architecture performs better than others in more accurately predicting next-frame. The paper is clearly written and the evaluation is based on other proposed similar architectures. For the moving MNIST they compared their model against the vanilla convLSTM with three gates and no peephole connections, based on previous work which has shown that it exceeds the accuracy performance of other LSTM based approaches. The results show that the training time is reduced and the standard error alike. The only limitations is that more databases could have been used to demonstrate the enhancement in performance.
