Other teams that are not among official entries, but among unofficial entries:

1. HeartBeats: SE-ResNet + Sign Loss + Model Ensemble

Aizip-ECG-team and Proton had high score on the hidden test set, but did not submitted papers, hence not described here.

Conference Website and Conference Programme

Website, Programme, IEEE Xplore, Poster

Data Preparation

One can download training data from GCP,
and use python prepare_dataset -i {data_directory} -v to prepare the data for training

Deep Models

Deep learning models are constructed using torch_ecg, which has already been added as a submodule.

Final Results

Final results are on the leaderboard page of the challenge official website or one can find in the offical_results folder.
