NeurIPS 2020 FAQ

Last updated: March 1, 2020

We will update this page with questions (and answers) as they arise. Please check back regularly. If you do not find an answer to your question here, you are welcome to contact the NeurIPS 2020 program chairs at, but please make sure that you have read the call for papers and the author guidelines (as well as this document) first!



  • I can’t see the reviews for my submission in CMT anymore. Is this normal? Answer: During the discussion and decision period, yes this is normal. After the author response is closed, reviews are not available anymore to allow reviewers to update them based on the author feedback. Reviews will become available again when decisions are released.

  • Will reviewers see that my paper is a resubmission (was previously rejected)? Answer: ACs and SACs will be able to see the author resubmission disclosure, but only after the early reject phase is complete. They can choose to share the information with reviewers during the discussion phase if they feel it is relevant.

Author Response

  • Can I submit a revised version of my submission as part of my author response? Answer: No. You may only provide a 1-page PDF response, following the provided stylefile. If your paper is accepted, then you will be able to submit a revised and final version of your paper.

Submission format and content

  • I would like to write my paper using Microsoft Word, but I don’t see a template. Can you provide one? Answer: No. The Microsoft Word template has been discontinued. Authors must use the NeurIPS 2020 LaTeX style file.

  • Does the eight-page limit include references? Answer: No. The page limit refers to content pages only; additional pages containing only references are allowed.

  • Does the eight-page limit include the Broader Impact section? Answer: No. The Broader Impact section can go on the additional pages, before the references.

  • Do I have to complete the Broader Impact section? Answer: Yes, please include the section. However, if your work is very theoretical or is general enough that there is no particular application foreseen, then you are free to write that a Broader Impact discussion is not applicable.

  • How should I write the Broader Impact section? Answer: For additional motivation and general guidance, read Brent Hecht et al.’s white paper and blogpost. For an example of such a discussion, see sec. 4 in this paper from Gillick et al. 

  • Can my submission be rejected solely on the basis of the Broader Impact Section? Answer: No. Reviewers will be asked to rate a submission based on the evaluation criteria. They will also be asked to check whether the Broader Impact is adequately addressed. In general, if a paper presents theoretical work without any foreseeable impact in the society, authors can simply state “This work does not present any foreseeable societal consequence”. If a paper presents a method or an application that might have reasonable chances to have some broader impact, authors can discuss along the following lines: “This work has the following potential positive impact in the society…. At the same time, this work may have some negative consequences because… Furthermore, we should be cautious of the result of failure of the system which could cause...” 


Submission process

  • I missed the abstract submission deadline. Can I still submit a full paper? Answer: No. The abstract submission deadline is firm.

  • Will you extend the full paper deadline? Answer: No. The full paper deadline is firm.

  • Is there a limit to the number of submissions I can be listed as an author on? Answer: No. But please make sure that your submissions are distinct and sufficiently substantial (‘slicing too thin’ is a type of dual submission violation; see the Call for Papers).

  • Can I submit supplementary material after the deadline? Answer: Yes. To avoid overloading CMT, the deadline for supplementary material is one week after the paper deadline. Check the call for papers for the exact day and time.

  • Can I change any field in the submission form after the deadline? Answer: The author order and list are final after the abstract submission deadline. All the other fields can be changed till the actual paper submission deadline. Note that title and abstract must not be changed substantially, otherwise the paper may be desk rejected. Title and abstract entered after the abstract submission deadline will be used for bidding by reviewers. 

  • How do I submit supplementary material? Answer: First upload your submission. You will then be able to upload supplementary material from the author console.

  • I didn’t receive an email confirmation from CMT. Did I upload my submission successfully? Answer: CMT will not send you an email confirmation. If you can see your submission listed in the author console, then you uploaded it correctly. If you’re still worried, you can download the PDF and check that the file is the same as the file you uploaded.

  • Can I withdraw my submission? Answer: Yes. You can withdraw your submission at any point in the reviewing process. For statistical purposes, we will count a submission as “rejected” if it is withdrawn after reviews have been made available to authors. 

Dual submissions

  • Can I submit work to NeurIPS that is currently in submission to another archival venue? Answer: No. The NeurIPS policy on dual submissions explicitly prohibits this. You need to withdraw your submission from the other venue before submitting to NeurIPS.

  • Can I submit an abstract to NeurIPS which belongs to a work that is currently in submission to another archival venue? Answer: Yes. The NeurIPS policy on dual submissions applies from the full paper submission deadline to the notification date, so the abstract can be submitted. However the dual submission needs to be resolved (either by withdrawing or being rejected from the other venue) before submitting a full paper to NeurIPS.

  • Can I submit work to NeurIPS and then later submit the same work to another archival venue while it is still under review at NeurIPS? Answer: No. The NeurIPS policy on dual submissions explicitly prohibits this. You need to withdraw your submission from NeurIPS first.

  • Can I submit work that is in submission to, has been accepted to, or has been published in a non-archival venue (e.g. a workshop without any official proceedings)? Answer: Yes.

  • Can I submit work to NeurIPS and then later submit the same work to a non-archival venue while it is still under review at NeurIPS? Answer: Maybe. It depends on the other venue’s policy on dual submissions.

  • Can I put my NeurIPS submission on arXiv? Answer: Yes. Note that reviewers will be instructed not to actively look for such preprints (as they compromise double-blind reviewing) but encountering them will not constitute a conflict of interest. 

CMT problems

  • Help! I can’t log into CMT! Answer: First make sure that you are using the correct email address. You need to log in using the email address that is associated with your submission. (If your submission was uploaded by one of your co-authors, please ask them which email address they used for you in CMT.) If you have forgotten your password, you can reset it by clicking “Forgot your password?” on the NeurIPS 2020 CMT log-in page.

  • My CMT account has been locked due to too many failed login attempts. Can you unlock it? Answer: No, but CMT can. Please contact the CMT support team directly (and provide your email address).

  • CMT seems to be very slow. What should I do? Answer: Sometimes CMT is very slow. We suggest you to try again at another time. If you continue to experience technical problems with CMT, please contact the CMT support team directly.

  • Oops! I misspelled the name of my co-author when uploading our submission and now they are grumpy at me. How can I correct their name? Answer: You need to ask your co-author to log in their CMT account (which is associated with their email address) and change it themselves by clicking on their name in the top-right corner of the screen.
