Machine Learning, Deep Learning, Recommender Systems
Senior Research Scientist at Telefonica Research in lively Barcelona.
My research in Machine Learning and Recommender Systems was awarded with three best paper awards at ECML/PKDD 2013, RecSys 2012 and ECML 2008. I regularly serve as a Senior PC at ACM RecSys and have been a PC member for KDD, WWW, WSDM, ICML, NIPS, ECML/PKDD.
Received my Ph.D. in Machine Learning from the Vienna University of Technology while being a frequent visitor at the Statistical Machine Learning group at NICTA in Canberra, Australia.
