Artyom Gadetsky
I am 2nd year PhD student at MLBio lab, EPFL in Lausanne, supervised by Maria Brbic. Currently, I am working on unsupervised transfer and representation learning. Previously, I was a researcher at CS HSE and BayesGroup supervised by Dmitry Vetrov, 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 real-life problems.

An approach to perform fully unsupervised transfer on a downstream dataset given representation spaces of foundation models. Although being fully unsupervised, our approach outperforms CLIP zero-shot transfer and sometimes matches optimal supervised performance!
