Wavelet Fourier Diffuser: Frequency-Aware Diffusion Model for Reinforcement Learning 事件

Wavelet Fourier Diffuser: Frequency-Aware Diffusion Model for Reinforcement Learning arXiv:2509.19305v2 Announce Type: replace-cross Abstract: Diffusion probability models have shown significant promise in offline reinforcement learning by directly modeling trajectory sequences. However, existing approaches primarily focus on time-domain features while overlooking frequency-domain features, leading to frequency shift and degraded performance according to our observation. In this paper, we inves
