Our research aims to narrow the gap between theoretically well-understood and practically relevant machine learning. Research questions concern for instance: To demonstrate the practical effectiveness of novel learning algorithms, we apply them in Chemistry, Material Science, Electrical Engineering, Computer Games, Humanities, etc.
