Follow me on twitter: @t3kcit

I'm doing my PhD in computer vision and machine learning at the university of Bonn. My interests include image segmentation, Bayesian non parametric methods, probabilistic graphical models, kernel methods, structured learning, multi-instance learning, large scale learning and CUDA. Also other things.

I start to consider myself a Python geek and I am trying to contribute to scikit-learn whenever I have time.
