Marius Kloft is interested in the foundations of statistical machine learning in general and particularly in multiple kernel learning and learning from non-i.i.d. observations.

Marius earned his M.S. in Mathematics from U Marburg in 2006 with a thesis in algebraic geometry and his Ph.D. in Computer Science from TU Berlin in 2011, where he was advised by  Klaus-Robert Müller. He was co-advised by Gilles Blanchard (U Potsdam), and by Peter L. Bartlett (UC Berkeley) during his one-year research visit at UC Berkeley from Fall 2009 to Fall 2010.  Since Dec 2012 he is a joint postdoctoral fellow at Courant Institute & MSKCC, working with Mehryar Mohri and Gunnar Rätsch, respectively.

Marius had been working on several aspects of multiple kernel learning: (non-sparse) regularization strategies, generalization bounds, unified framework, and novelty detection. He has co-organized workshops on new directions in multiple kernel learning and multi-task learning at NIPS 2010 and 2013, respectively. His dissertation on Lp-norm multiple kernel learning was nominated by TU Berlin for the Doctoral Dissertation Award of the German Chapter of the ACM (GI).
