Improving Policy Optimization with Generalist-Specialist Learning

1 code implementation26 Jun 2022 Zhiwei Jia, Xuanlin Li, Zhan Ling, Shuang Liu, Yiran Wu, Hao Su

Generalization in deep reinforcement learning over unseen environment variations usually requires policy learning over a large set of diverse training variations.

Learning to Act with Affordance-Aware Multimodal Neural SLAM

1 code implementation24 Jan 2022 Zhiwei Jia, Kaixiang Lin, Yizhou Zhao, Qiaozi Gao, Govind Thattai, Gaurav Sukhatme

With the proposed Affordance-aware Multimodal Neural SLAM (AMSLAM) approach, we obtain more than 40% improvement over prior published work on the ALFRED benchmark and set a new state-of-the-art generalization performance at a success rate of 23. 48% on the test unseen scenes.
