How Does the Lagrangian Guide Safe Reinforcement Learning through Diffusion Models?

ICML 2026poster

Diffusion policy sampling enables reinforcement learning (RL) to represent multimodal action distributions beyond suboptimal unimodal Gaussian policies. However, existing diffusion-based RL methods primarily focus on offline setting for reward maximization, with limited consideration of safety in on…

ResKoopNet: Learning Koopman Representations for Complex Dynamics with Spectral Residuals

ICML 2025poster

Analyzing the long-term behavior of high-dimensional nonlinear dynamical systems remains a significant challenge. While the Koopman operator framework provides a powerful global linearization tool, current methods for approximating its spectral components often face theoretical limitations and depen…
