Text2Reward: Automated Dense Reward Function Generation for Reinforcement Learning

1 code implementation20 Sep 2023 Tianbao Xie, Siheng Zhao, Chen Henry Wu, Yitao Liu, Qian Luo, Victor Zhong, Yanchao Yang, Tao Yu

Unlike inverse RL and recent work that uses LLMs to write sparse reward codes, Text2Reward produces interpretable, free-form dense reward codes that cover a wide range of tasks, utilize existing packages, and allow iterative refinement with human feedback.

Causal Discovery of Flight Service Process Based on Event Sequence

no code implementations28 Apr 2021 Zhiwei Xing, Lin Zhang, Huan Xia, Qian Luo, Zhao-xin Chen

In the existing ground support research, there has not yet been a process model that directly obtains support from the ground support log to study the causal relationship between service nodes and flight delays.
