Since many MLT community members mentioned that they would like to participate in Kaggle competitions I think this would be a great opportunity for us! We could hold regular Kaggle meetings, co-located with our study group. Who is interested in this competition?
Something that is very important for Japan: Kaggle launched its Earthquake Prediction competition with $50.000 prize money. https://www.kaggle.com/c/LANL-Earthquake-Prediction
