Large Language Model as a Policy Teacher for Training Reinforcement Learning Agents

1 code implementation22 Nov 2023 ZiHao Zhou, Bin Hu, Chenyang Zhao, Pu Zhang, Bin Liu

By incorporating the guidance from the teacher agent, the student agent can distill the prior knowledge of the LLM into its own model.

SwinLSTM:Improving Spatiotemporal Prediction Accuracy using Swin Transformer and LSTM

1 code implementation19 Aug 2023 Song Tang, Chuang Li, Pu Zhang, RongNian Tang

In this paper, we propose a new recurrent cell, SwinLSTM, which integrates Swin Transformer blocks and the simplified LSTM, an extension that replaces the convolutional structure in ConvLSTM with the self-attention mechanism.

Heterogeneous Trajectory Forecasting via Risk and Scene Graph Learning

1 code implementation2 Nov 2022 Jianwu Fang, Chen Zhu, Pu Zhang, Hongkai Yu, Jianru Xue

Heterogeneous trajectory forecasting is critical for intelligent transportation systems, but it is challenging because of the difficulty of modeling the complex interaction relations among the heterogeneous road agents as well as their agent-environment constraints.

Trajectory Forecasting from Detection with Uncertainty-Aware Motion Encoding

no code implementations3 Feb 2022 Pu Zhang, Lei Bai, Jianru Xue, Jianwu Fang, Nanning Zheng, Wanli Ouyang

Trajectories obtained from object detection and tracking are inevitably noisy, which could cause serious forecasting errors to predictors built on ground truth trajectories.

SR-LSTM: State Refinement for LSTM towards Pedestrian Trajectory Prediction

1 code implementation CVPR 2019 Pu Zhang, Wanli Ouyang, Pengfei Zhang, Jianru Xue, Nanning Zheng

In order to address this issue, we propose a data-driven state refinement module for LSTM network (SR-LSTM), which activates the utilization of the current intention of neighbors, and jointly and iteratively refines the current states of all participants in the crowd through a message passing mechanism.
