Roman V. Shapovalov
I am currently a PhD student in the Mathematical Prediction Department at Moscow State University. My research interests include (but are not limited to) machine learning, probabilistic graphical models, and their applications to computer vision. My advisor is Dmitry Vetrov. We collaborate with Pushmeet Kohli as a part of Microsoft Research programs in Russia.
My PhD thesis is about structural learning for semantic segmentation of images and point clouds. Specifically, I now study max-margin learning of CRFs with various loss functions, which is useful, inter alia, for learning from weakly supervised data. I also have some project ideas I would be happy to implement if only I had enough time, such as a simple home video surveillance system (which recognizes faces of friends coming by and greets them), or a content-based music recommendation system (although recent Google's interest to industrial-quality music analysis ruins my motivation). However, if you are ready for collaboration, feel free to contact me.

I have some code on github.
GML LidarK Library — the library for LIDAR data processing. Currently, only the indexing data structure is implemented. It allows performing spatial queries in 3D space. The code is C++, MATLAB wrapper is also available.
GML BOLT — the toolkit for on-line learning from imbalanced streams. It contains an on-line implementation of the Random Forest algorithm.
Non-research interestsI enjoy snowboarding, cycling, urban orienteering and editing Wikipedia. I also learn to play electric guitar. And those are only virtuous ones! ;)
