Planning Neural Dynamics with Lie Group Embedding through Supervised Projective Manifold Learning

This research proposes Lie group embedded dynamical neural networks (LieEDNN) and associated learning algorithms for achieving learnable and stable dynamics on underlying manifolds. It leverages Lie groups' powerful representation capabilities to address challenges in neural network interactions and nonlinear representation spaces, with applications in robotics, graphics, and control.

Provably Learning Diffusion Models under the Manifold Hypothesis: Collapse and Refine

This paper provides a theoretical explanation for the efficiency of diffusion models in learning the score function for high-dimensional data supported on low-dimensional manifolds. It identifies a "collapse-and-refine" mechanism driven by the geometry of the score function, where the denoising map projects onto the data manifold and refines the intrinsic density.
