Семинар HDI Lab: Building light Schrödinger bridges

Мероприятие завершено

В четверг, 6 июня, в 14:40 состоится очередной семинар. С докладом выступят Александр Коротин, Никита Гущин и Сергей Холькин (Сколтех).

Building light Schrödinger bridges

Schrödinger Bridges (SB) have recently gained attention of the ML community as a promising extension of classic diffusion models, which are also interconnected to the Entropic Optimal Transport (EOT). Despite the recent advances in the field of computational Schrödinger Bridges (SB), most existing SB solvers are still heavy-weighted and require complex optimization of several neural networks. 

We address this issue and propose two novel light solvers for this problem: LightSB and LightSBM. Both utilize the optimal structure of Schrödinger Bridges but in different ways. The LightSB solver allows direct minimized KL-divergence with the ground-truth solution, knowing only start and end marginals. The LightSBM solver is based on bridge matching and introduces the new concept of "optimal projection," allowing the Schrödinger Bridge to be solved in one bridge-matching iteration.
