First off, thanks to the organizers for curating this competition, we learned a lot and enjoyed the process. However, there are some points we would like to express, to be considered in future for a more fair competition.
-
Submission limits in the Phase 2 felt uneven across time zones. Some teams including us had 20 attempts while others had 30. In this phase where the errors were so little between the groups, each attempt mattered.
-
We received the final-round email only one day before the deadline. Of course we checked the website frequently, but communication could be better.
-
The email said Final Ranking is the average rank across both phases, but current final rankings doesn’t seem to be the average rankings. Is it based on NMAE or only the ranking?
Once again, thanks to the organizers and congrats to the winners!
