About

I am an assistant professor at the Czech Technical University in Prague and a researcher in the Visual Recognition Group.

I graduated Kiev Polytechnical Institute and received a PhD from Czech Technical University in Prague in the area of discrete optimization for computer vision. In 2014–2017 postdoctoral researcher at Graz University of Technology. Since 2017 continued on the academic track at CTU.

I am generally interested in methods and models of statistical machine learning, with the recent focus on discrete neural networks and their applications in computer vision and language modeling.
