The Datathon@LISH contest is now officially opened!!

To get started, please fill out the pre-contest survey. Once completed, you will receive a follow-up email with the link to the contest notebook, where you start working on the problem. The total setup process will take about 15 minutes and involve a decent amount of reading. You have until Sunday Feb. 13th at 5PM EST to submit predictions.

If you plan to work with a partner during the contest, please submit only one survey response for your team. You are free to change your team status at this point, regardless of whether you originally registered as an individual or a team. However, this survey will be the final confirmation of whether you plan to work as an individual or as a pair – you cannot change your status mid-contest.

If you have any questions throughout the contest, please email this inbox ( directly. We will be actively monitoring the inbox between 5-10PM ET Friday, 8AM-10PM ET Saturday, and 8AM-5PM ET Sunday.

PS: Throughout the contest please be sure to monitor your spam/junk folder. Alternatively, please whitelist our datathon email accounts ( and Here are some instructions for doing this in Gmail and Outlook.

The event is only 9 days away; watch the below video and read on to learn more about the contest!

  1. Contest Timeline. The event will take place on Friday, February 11th, starting at 5pm ET and ending on Sunday, February 13th, at 5pm ET. Work time is flexible and self-determined during the contest (you don’t need to start exactly at 5PM on Friday). We recommend blocking off at least 8 hours to work on the problem to be competitive. The winner announcement / awards ceremony will be Wednesday, February 16th 5:30-6:00 PM ET. You can see the full contest timeline here.

  2. Contest Problem. You will be working on a binary prediction problem relevant to a challenge faced by many developing countries. Full details on the problem will be released at the start of the contest.

  3. Two Contest Tracks. To increase your chances of winning, we are running TWO parallel tracks, each with slightly different rules, different contest rankings, and prize winners. Your team will be randomly assigned to one of these tracks at the start of the contest. This doubles your chances of winning the contest!

  1. Calendar Hold for Event. We’ve created a calendar hold for the event spanning the weekend of February 12th. Note that the exact start and end times are to-be-determined, but contest will be open for about 48 hours (on the shorter end for datathons). Work time is flexible and self-determined during the contest. We recommend blocking off at least 8 hours to work on the problem to be competitive.

  2. Team Entry. Our datathon is open to individuals and pairs. Even if you originally registered as an individual, you can still choose to participate with a partner – just be sure to have your partner register via the datathon website before the event. We’ll only need to know if you plan on entering as a team at the very start of the competition on 02/12. (We unfortunately cannot help you find a partner for the competition.)

  3. Prizes. As mentioned on this website, there will be prizes for the top 10 teams in each contest track (1st: $1000, 2nd: $500, 3rd: $250, top 10: $50 Amazon Gift). We will try to scale the number of parallel contest tracks to ensure competitiveness, such that roughly the top 10% of teams will win these bigger monetary prizes. Every eligible team that submits predictions that beat our benchmark score will be eligible for our participation prize ($10 Amazon Gift Card or Contest t-shirt). Update 02/01: Due to logistical challenges in delivering t-shirts remotely, we have removed it as an option for a participation prize. All teams reaching the benchmark score will get a $10 Amazon gift card.

  4. Invite Your Friends! We’d love to have as broad participation as possible, so please forward this event website to your eligible friends and have them register if you think they would be interested in participating. Having more friends participate also increases your chances that one of them can buy you dinner using prize money from the competition :)

  5. Questions about the Contest? We've updated our Website FAQs in response to questions that we've gotten through our registration form. If you have any further questions or are no longer able to participate in the competition, feel free to let us know by replying to this email directly!
