You may be interested in the ChaLearn Automatic Machine Learning challenge http://www.codalab.org/AutoML (5 rounds until June 2015, 30 datasets!): the goal is to design the perfect machine learning “black box” capable of performing all model selection and hyper-parameter tuning without any human intervention.
Until February 14 you can submit learning machines OR predictions to win 2 sets of $3000 prizes in 2 tracks:
- “Tweakathon 0”: result or code submission on well known sample datasets (preparation phase)
- “AutoML 1”: code submission on binary classification problems (novice phase) Sample submissions are provided to easily get started.
