Cooperative Policy Learning with Pre-trained Heterogeneous Observation Representations

1 code implementation24 Dec 2020 Wenlei Shi, Xinran Wei, Jia Zhang, Xiaoyuan Ni, Arthur Jiang, Jiang Bian, Tie-Yan Liu

While adopting complex GNN models with more informative message passing and aggregation mechanisms can obviously benefit heterogeneous vertex representations and cooperative policy learning, it could, on the other hand, increase the training difficulty of MARL and demand more intense and direct reward signals compared to the original global reward.

Graph Attention Multi-agent Reinforcement Learning

Semi-Supervised Few-Shot Atomic Action Recognition

1 code implementation17 Nov 2020 Xiaoyuan Ni, Sizhe Song, Yu-Wing Tai, Chi-Keung Tang

Despite excellent progress has been made, the performance on action recognition still heavily relies on specific datasets, which are difficult to extend new action classes due to labor-intensive labeling.
