Artyom Gadetsky
I am Junior Research Scientist at CS HSE and Bayesgroup, supervised by Dmitry Vetrov. Currently I'm working on stochastic optimization w.r.t. discrete distributions over structured objects such as graphs, permutations, etc. Generally speaking I am interested in different applications of probabilistic modelling to solve general machine learning problems as well as reallife problems. Also, I'm a teaching fellow at Continuous Optimization course at CS HSE.
