A Hierarchical Hybrid Learning Framework for Multi-agent Trajectory Prediction

no code implementations22 Mar 2023 Yujun Jiao, Mingze Miao, Zhishuai Yin, Chunyuan Lei, Xu Zhu, Linzhen Nie, Bo Tao

In this paper, we propose a hierarchical hybrid framework of deep learning (DL) and reinforcement learning (RL) for multi-agent trajectory prediction, to cope with the challenge of predicting motions shaped by multi-scale interactions.

Toward UL-DL Rate Balancing: Joint Resource Allocation and Hybrid-Mode Multiple Access for UAV-BS Assisted Communication Systems

no code implementations16 Nov 2021 Haiyong Zeng, Xu Zhu, Yufei Jiang, Zhongxiang Wei, Sumei Sun

To the best of our knowledge, this is the first work to explicitly investigate joint UL-DL optimization for UAV assisted systems under heterogeneous requirements.

A Semi-Blind Multiuser SIMO GFDM System in the Presence of CFOs and IQ Imbalances

no code implementations14 Oct 2020 Yujie Liu, Xu Zhu, Eng Gee Lim, Yufei Jiang, Yi Huang

A low-complexity semi-blind joint estimation scheme of multiple channels, CFOs and IQ imbalances is proposed.

Lipschitz Bandit Optimization with Improved Efficiency

no code implementations25 Apr 2019 Xu Zhu, David B. Dunson

We consider the Lipschitz bandit optimization problem with an emphasis on practical efficiency.

Stochastic Lipschitz Q-Learning

no code implementations24 Apr 2019 Xu Zhu, David Dunson

To the best of our knowledge, this is the first analysis in the model-free setting whose established regret matches the lower bound up to a logarithmic factor.
