Scores

These tables contain scores for the 12-lead, 6-lead, 4-lead, 3-lead, and 2-lead versions of the hidden validation and test sets. The 2021 Challenge webpage and 2021 Challenge paper describes the lead combinations and the validation and test data sources. We also included an all-lead score in the tables, which is computed as the mean of the 12-lead, 3-lead, and 2-lead scores.

We used the Challenge scoring metric that we implemented in the evaluation code repository to rank the official entries on the test set. We sorted the unofficial entries alphabetically by team name.

In these tables, you can find the following information:
