I know this is a very general question, but I'm looking for interesting machine learning projects, and wondered if there is anything I can waste cpu cycles on that actually matters. Particularly scientific data that might uncover a previously unknown relationship or something interesting. Or maybe data where someone might find a better model actually useful for something.
I'm aware of Kaggle, but with 100's of people, including experts, already working on every dataset, there isn't much room to find something new.
