Every team must be registered in order to be eligible for the subsequent test submissions.

Each team can optionally submit one initial test prediction per dataset. The prediction will be evaluated on 5% of test data, and the performance will be made public in our initial leaderboards. Although the performance here does not affect the winner selection, we encourage all the teams to try the initial submission to ensure the smooth final test submission.

Each team submits its final test prediction, which will be evaluated over the entire test data.


June 10th, 2021: Winner announcement

Top 3 winners for each dataset will be announced (in total of 9 winners). Results of all the final test submissions will be also made publicly available.


June 15th, 2021: Code submission deadline for the winners

For the winners, we require public Github code submission to reproduce their solutions. The winners are finalized once they provide the public Github code. The Github repository needs to remain public even after the KDD Cup. We will publicize the code on our webpage.
