Learning from Random Demonstrations: Offline Reinforcement Learning with Importance-Sampled Diffusion Models

no code implementations30 May 2024 Zeyu Fang, Tian Lan

It iteratively leverages a guided diffusion world model to directly evaluate the offline target policy with actions drawn from it, and then performs an importance-sampled world model update to adaptively align the world model with the updated policy.

Rethinking Propagation for Unsupervised Graph Domain Adaptation

1 code implementation8 Feb 2024 Meihan Liu, Zeyu Fang, Zhen Zhang, Ming Gu, Sheng Zhou, Xin Wang, Jiajun Bu

Motivated by our empirical analysis, we reevaluate the role of GNNs in graph domain adaptation and uncover the pivotal role of the propagation process in GNNs for adapting to different graph domains.
