About

Patrick

I'm a machine learning PhD student in the group of Prof. Joachim M. Buhmann at ETH Zurich, Switzerland.

Research

My main research interest is centered around structured output prediction and learning. I'm trying to come up with novel approaches for learning such models, which hopefully lead to more efficient approximate training. I'm also interested in the very related topic of inference in graphical models.

Publications

I also try to keep my Google scholar profile up to date.
