New data for the PhysioNet/Computing in Cardiology Challenge 2020

We have begun the official phase of the Challenge. Please find a new tranche of data with SNOMED-CT codes as diagnoses. Please note that there are some errors or debatable labels in some of the data. Part of the Challenge will be working out how to deal with these issues. In the next few weeks, we will release more data and reopen the scoring system with a new scoring metric.
