One Category One Prompt: Dataset Distillation using Diffusion Models

no code implementations11 Mar 2024 Ali Abbasi, Ashkan Shahbazi, Hamed Pirsiavash, Soheil Kolouri

However, traditional dataset distillation approaches often struggle to scale effectively with high-resolution images and more complex architectures due to the limitations in bi-level optimization.

Efficient Solvers for Partial Gromov-Wasserstein

no code implementations6 Feb 2024 Yikun Bai, Rocio Diaz Martin, Hengrong Du, Ashkan Shahbazi, Soheil Kolouri

The partial Gromov-Wasserstein (PGW) problem facilitates the comparison of measures with unequal masses residing in potentially distinct metric spaces, thereby enabling unbalanced and partial matching across these spaces.

Stereographic Spherical Sliced Wasserstein Distances

Equivariant vs. Invariant Layers: A Comparison of Backbone and Pooling for Point Cloud Classification

no code implementations8 Jun 2023 Ashkan Shahbazi, Abihith Kothapalli, Xinran Liu, Robert Sheng, Soheil Kolouri

Our findings reveal that: 1) complex pooling methods, such as transport-based or attention-based poolings, can significantly boost the performance of simple backbones, but the benefits diminish for more complex backbones, 2) even complex backbones can benefit from pooling layers in low data scenarios, 3) surprisingly, the choice of pooling layers can have a more significant impact on the model's performance than adjusting the width and depth of the backbone, and 4) pairwise combination of pooling layers can significantly improve the performance of a fixed backbone.
