Readiness requirements

Review the key details below, or download the complete checklist with every stored source-backed requirement.

Abstract length

  • Provide an author-written abstract of no more than 200 words.
  • an abstract that does not exceed 200 words.

Keywords

  • Articles must be accompanied by a cover letter (in PDF, using this LaTeX template or plain text format) containing all of the below: List of keywords from the article.

Reference style

  • Articlo formats your supplied references to the journal's stored style and checks that citations match the reference list; source validity is not verified.

Figure and table rules

  • Keep every figure and table numbered, captioned, and cited in the manuscript.

Funding statement

  • Add or confirm the author-written Funding statement; Articlo flags it if author input is still needed.
  • You should disclose interactions with any entity that could be considered broadly relevant to the work, even if the funding was not used to support the submitted work, and regardless of the amount of compensation.

  • This question refers to any aspect of the submitted work, including but not limited to personal funding, data collection, data evaluation, computing hardware, cloud computing services, or programming support.

Competing interests

  • Articles must be accompanied by a cover letter (in PDF, using this LaTeX template or plain text format) containing all of the below: Declaration of possible conflicts of interest; in particular, name all action editors that have recently collaborated with authors of the submission.

Cover letter

  • Provide the claims and editor-specific context for the cover letter; Articlo creates an editable companion without inventing content.
  • Further, papers above 50 pages require a note of justification in the cover letter, and may be desk rejected. (Note that these page counts include appendices.).

  • Articles must be accompanied by a cover letter (in PDF, using this LaTeX template or plain text format) containing all of the below: Suggestions of 3 to 5 reviewers.
  • Articles must be accompanied by a cover letter (in PDF, using this LaTeX template or plain text format) containing all of the below: Suggestions of 3 to 5 action editors that seem best suited to handle the submitted manuscript (Note: from the list of Action Editors, NOT editorial board reviewers).
  • Articles must be accompanied by a cover letter (in PDF, using this LaTeX template or plain text format) containing all of the below: Disclosure of any previous publications by the author(s) that significantly overlap with the submission.
  • Publication When a paper is accepted, authors must sign an agreement granting a CC-by license to the public, which allows for publication in JMLR online by JMLR, Inc. and in a print-archive edition by Microtome Publishing.

Supplementary files

  • Include every cited supplementary file and use matching labels in the manuscript.
  • In all cases, authors must notify JMLR about previous publication at the time of submission, attach the previous paper as a supplementary document, and explain the differences from their prior work.

Title page and author information

  • If an exceptional situation arises, the corresponding author must email the Editorial Office before a final decision is rendered, supplying (i) a detailed rationale, and (ii) written consent from all current and proposed authors.

Preprints and prior publication

  • We strongly encourage authors to include such appendices along with their papers. (Note: if an online appendix contains source code, we will require you to sign a release form prior to publication freeing us from liability.) We also strongly encourage authors to submit their data sets to the UCI Machine Learning Repository.

Other submission requirements

  • Content Papers must be concise and complete; manuscripts should be carefully proofread and polished.
  • All claims should be clearly articulated and supported either by empirical experiments or theoretical analyses.

  • When appropriate, authors are encouraged to implement their work and to demonstrate its utility on significant problems; any experiments reported should be reproducible.
  • Papers describing systems should clearly describe the contributions or the principles underlying the system.
  • In general, it should be clear how the work advances the current state of understanding and why the advance matters.
  • Papers should report on what was learned in doing the work, rather than merely on what was done.
  • Authors must clearly acknowledge the contributions of their predecessors, and situate their submission in the context of the broader machine learning research literature.
  • If a paper introduces new terminology or techniques, it should also explain why current terminology or techniques are insufficient.
  • Submissions must be typeset in LaTex using the JMLR LaTeX style file described in the authors guide.
  • Accepted papers may still require minor revisions, but those are usually checked only by the action editor.
  • Only PDF files should be submitted.
  • You can then confirm that your manuscript has been received by selecting (at the top of the page) "manuscript listing" followed by "author." Your manuscript's ID tag should appear along the left-hand side.
  • Papers longer than 35 pages will take a longer time to review and may be rejected if an AE and reviewers cannot be found.
  • JMLR occasionally publishes surveys by invitation from the editorial board; we do not consider unsolicited survey papers.
  • Submissions that do not meet these criteria may be returned unreviewed.
  • Originality Submissions to JMLR cannot have been published previously in any other journal.
  • Rejection may or may not be accompanied by the encouragement to resubmit.
  • JMLR may take additional steps, such as (but not necessarily limited to) contacting the program chairs of the major machine learning conferences, contacting the editors of other journals, contacting the places of employment of the accused authors, and rejecting other manuscripts under submission to JMLR by the same authors.

Manuscript structure

  • Papers describing theoretical results should also discuss their practical utility.

Authorship and originality

  • Articles must be accompanied by a cover letter (in PDF, using this LaTeX template or plain text format) containing all of the below: Confirmation that all co-authors are aware of the current submission and consent to its review by JMLR.
