Christos Tzelepis received  the Diploma degree in Electical and Computer Engineering from Aristotle University of Thessaloniki, Greece, in 2011. During his diploma thesis, he focused on machine learning techniques with training data of variable reliability. Currently, he is a PhD candidate in Electonic Engineering and Computer Science at Queen Mary, University of London, within the field of discriminative machine learning, under the supervision of Dr. Ioannis Patras and Dr. Vasileios Mezaris. His research interests are in the areas of machine learning, content-based multimedia information management and image and video analysis.
