PhysioNet-CinC-Challenge 2020 - Classification of 12-lead ECGs

Figure 1: This plot is made by using ecg plot [1] and the ECG data is from the PTB Diagnostic DB [2].

This project is based on the work we did in the PhysioNet/Computing in Cardiology Challenge 2020. This paper [3] describes the Challenge and this paper discribes our contribution in this challenge.

Data:

The data set in this project contains 43.101 ECGs and comes from six different sources. Table 1 show the six sources.

Table 1: The table lists the six different sources used in the data set in this project

Data set number	Name
1	China Physiological Signal Challenge 2018
2	China Physiological Signal Challenge 2018 Extra
3	St.Petersburg Institute of Cardiological Technics
4	PTB Diagnostics
5	PTB-XL
6	Georgia 12-Lead ECG Challenge Database

Get access to the data:

To get access to the data used in this study you can either download it from https://physionetchallenges.github.io/2020/#data or download the same data set from Kaggle. To use the codes in this repository you should sign up for a Kaggle account and get a Kaggle API token and use this to get access to the Kaggle data set from Google Colab. Google Colab Pro was used to get sufficient GPU power and enough runtime.

How to get your Kaggle API token:

1. Log in to your Kaggle account or sign up here
2. On the left side of the "edit profile"-button you click on the "Account"-option.
3. Scroll down to the API-section and click "Create New API Token"-button.
4. You will now have a file named kaggle.json. This is your API-token
5. You can upload the kaggle.json-file to the Google Colab notebook and then you are able to download datasets from Kaggle

Models:

10-fold cross-validated models:

Model number	Model	Link to Google Colab Notebook	Link to Notebook on github
1	FCN		Notebook
2	Encoder		Notebook
3	FCN + MLP		Notebook
4	Encoder + MLP		Notebook
5 & 6	Encoder + FCN (and Encoder + FCN + rule-based model)		Notebook
7 & 8	Encoder + FCN + MLP + (and Endcoder + FCN + MLP + Rule-based model)		Notebook

Plot the cross-validation results:

The results from the cross-validated models can be plotted with this notebook . The figures can be found here.
