ReVoLT: Relational Reasoning and Voronoi Local Graph Planning for Target-driven Navigation

no code implementations6 Jan 2023 Junjia Liu, Jianfei Guo, Zehui Meng, Jingtao Xue

However, most of them obtain robot actions directly from observations in an end-to-end manner via an incomplete relation graph, which is not interpretable and reliable.

A Multi-Modal States based Vehicle Descriptor and Dilated Convolutional Social Pooling for Vehicle Trajectory Prediction

no code implementations7 Mar 2020 Huimin Zhang, Yafei Wang, Junjia Liu, Chengwei Li, Taiyuan Ma, Chengliang Yin

Secondly, the LSTM encoder is used to encode the historical sequences composed of the vehicle descriptor and a novel dilated convolutional social pooling is proposed to improve modeling vehicles' spatial interactions.

Learning Scalable Multi-Agent Coordination by Spatial Differentiation for Traffic Signal Control

1 code implementation27 Feb 2020 Junjia Liu, Huimin Zhang, Zhuang Fu, Yao Wang

By extending the idea of Markov Chain to the dimension of space-time, this truly decentralized coordination mechanism replaces the graph attention method and realizes the decoupling of the road network, which is more scalable and more in line with practice.
