Getting Started

Everyone is expected to follow the Code of Conduct. We recommend to start by browsing the conference schedule. Read below to learn more about how to use all elements of the virtual conference site. Thank you to all the organizers who made NeurIPS 2021 possible.

System Requirements

To access the site you will need a modern browser with JavaScript enabled. The website uses several external tools, namely Rocket.Chat, Zoom, and GatherTown. The login is handled through single sign-on through the virtual portal. You will not need to download any special software.

A 10 mb of inbound bandwidth is recommended.

Navigating the Website

All of NeurIPS 2021 will be accessed through the main webpage. You may access all parts of the conference using the top menu bar. Check the Schedule to get an overview of when the live sessions for all events are taking place. You may navigate all the papers in the Papers section. You may search for titles and authors or look through all papers by skimming titles and bookmarking them. You can bookmark other sessions as well. If you go to your name in the top right corner and click on My Bookmarks in the dropdown menu, you can download the schedule with all sessions you bookmarked and you can import it in your calendar.

The Schedule and Papers pages may be a bit slower to load the first time you access them.


  • Each event has a live stream on the top of the page that you can watch during and after the presentation.
  • All recordings will be available about a month after the conference.

Poster Sessions

The poster sessions will be held in GatherTown. You can access posters in GatherTown by clicking "Visit Poster at Spot XX in Virtual World" on the paper's page.


All attendees with registration will automatically have access to Rocket.Chat, a separate Rocket.Chat account is not needed. If you have problems with Rocket.Chat try refreshing the page. If that does not work try logging out and then logging back in.

Each session has a Rocket.Chat channel. Questions for the speakers should be posted there. Other participants that are also interested in the question can comment or put emoji on the post to increase its visibility. Eventually, the moderator will select questions to ask the speaker. Speakers will be able to continue answering questions on Rocket.Chat after the end of their talk for approximately one hour.

Your current timezone: . (Note: the paper browser uses your system timezone.)

You can have the conference display the time in you timezone. We highly recommend picking a timezone based on a nearby city, especially if your area observes daylight savings time. Timezones are political and complex and thus confusing. Please check your timezone, and preferably choose a zone based on a city.

In previous conferences some attendees have noticed that the times shown on the virtual website appeared incorrect. The problem was that they chose a timezone that did not adjust for daylight savings time.
