G. Tolias - Γ. Τόλιας

Giorgos Tolias

I am an associate professor at CTU in Prague and a member of the Visual Recognition Group (VRG). I am currently leading a small team within VRG.

From 2014 to mid-2015 I was a postdoc at the LinkMedia team of Inria Rennes, while I obtained my Ph.D from the NTU of Athens in 2013, where I worked with the Image and Video Analysis Team (IVA). In the past, I have worked closely with Ondrej Chum, Herve Jegou, and Yannis Avrithis.

My research is on computer vision. I enjoy working on learning visual representation, especially in the limited supervision regime. A special focus is on recognition problems (i) for large category sets, (ii) with a fine granularity of labels, or (iii) under a distribution shift.
