The Living Dead

A few of you have pointed out, that there seem to be a few 'living dead' that are in hopsitals AFTER they (supposedly) died.

There are a few legitimate scenarios where this can happen (overlapping hospital stays) and there are a few that are clearly wrong.
So it may be a data error/honest mistake or the more sinister scenario: insurance fraud.

As it is: there is nothing I can do about it. You will have to deal with this.

Questions about the organization

There will be no leaderboard. While they may make it more exciting, I think they do more harm then good since I have seen many people overfitting the 'leaderbord' set.

Questions about the submission

Instructions will be posted here and on the competition website in the next weeks.

Questions about the Data

Please post any questions about the data here!
