I am a Sr. Research Scientist at Yahoo Research/Scalable Machine Learning team since March 2017. I have obtained my PhD degree in Machine Learning from the University of Szeged (Hungary) in 2009. After that, I was a postdoctoral fellow at the CNRS / University of Paris-Sud (France) where he worked on various aspects of boosting algorithm (base classifiers, improving training and prediction performance of AdaBoost, etc.) and learning to rank problems. Prior to joining to Yahoo Research, I worked as an assistant professor at Paderborn University (Germany).
