Hi!
Yes, in order to be eligible for the final ranking in the challenge, all you need to do is submit your results to the leaderboard by the end of March 15th.
However, each of the top 3 performing teams will have to submit a short technical report regarding their method in order to appear in the final challenge ranking.
After the challenge closes, the top performing teams will be notified by email and asked to write the technical report.
Best,
Jon Muhovič
