First, essential for the participation in the hackathon is that you sign the Non-Disclosure Agreement (NDA) to get access to the data provided via a private Github repository. The NDA will be part of the onboarding email that you receive the day before the hackathon.
Second, participation in the hackathon is all about getting and sharing knowledge about current modelling techniques. Unless, otherwise agreed on with the organizors, all project results and corresponding source codes should therefore be publicly available at the end of the hackathon.
Third, in order to be eligble for further funding of your machine learning journey after the hackathon, your project must be uploaded and documented in Devpost until Sunday night after the event.
