About the Authors Willi Richert has a PhD in Machine Learning and Robotics, and he currently works for Microsoft in the Core Relevance Team of Bing, where he is involved in a variety of machine learning areas such as active learning and statistical machine translation. This book would not have been possible without the support of my wife Natalie and my sons Linus and Moritz. I am also especially grateful for the many fruitful discussions with my current and previous managers, Andreas Bode, Clemens Marschner, Hongyan Zhou, and Eric Crestan, as well as my colleagues and friends, Tomasz Marciniak, Cristian Eigel, Oliver Niehoerster, and Philipp Adelt. The interesting ideas are most likely from them; the bugs belong to me.
