PhysioNet/CinC Challenge 2020 Results

This page contains the final scores for the 2020 PhysioNet/CinC Challenge:

  1. The official scores
  2. The unofficial scores
  3. The metrics per database of the official entries
  4. The per-class scoring metrics of the official entries on the validation data

We introduced a new scoring metric for this Challenge. We used this scoring metric to evaluate and rank the Challenge entries. We included several other metrics for reference. The area under the receiver operating characteristic (AUROC), area under the precision recall curve (AUPRC), and F-measure scores are the macro-average of the scores across all classes. The accuracy metric is the fraction of correctly diagnosed recordings, i.e., all classes for the recording are correct. These metrics were computed by the script. Please see the script for more details of these scores.

We included the scores on the following datasets:

  1. Validation Set: Includes recordings from the hidden CPSC and G12EC sets.
  2. Hidden CPSC Set: Split between the validation and test sets.
  3. Hidden G12EC Set: Split between the validation and test sets.
  4. Hidden Undisclosed Set: All recordings were part of the test sets.
  5. Test Set: Includes recordings from the hidden CPSC, G12EC, and undisclosed test sets.
