Ever wondered how card shuffling can help solve combinatorial problems like sorting, jigsaw puzzles, or TSPs?
Our ICLR 2025 (Oral) paper SymmetricDiffusers introduces a novel discrete diffusion model on finite symmetric groups to solve them in a unified and principled way!
Behavioral cloning+observation histories > behavioral cloning+the most recent observation? Surprisingly, it sometimes wonβt. This counter-intuitive phenomenon is referred to as copycat problem. Our ECCV2022 work proposes a novel imitation learning network to alleviate this issue.
