Radar Anti-jamming Strategy Learning via Domain-knowledge Enhanced Online Convex Optimization

no code implementations26 Feb 2024 Liangqi Liu, Wenqiang Pu, Yingru Li, Bo Jiu, Zhi-Quan Luo

The dynamic competition between radar and jammer systems presents a significant challenge for modern Electronic Warfare (EW), as current active learning approaches still lack sample efficiency and fail to exploit jammer's characteristics.

HyperAgent: A Simple, Scalable, Efficient and Provable Reinforcement Learning Framework for Complex Environments

no code implementations5 Feb 2024 Yingru Li, Jiawei Xu, Lei Han, Zhi-Quan Luo

To solve complex tasks under resource constraints, reinforcement learning (RL) agents need to be simple, efficient, and scalable, addressing (1) large state spaces and (2) the continuous accumulation of interaction data.

HyperDQN: A Randomized Exploration Method for Deep Reinforcement Learning

1 code implementation ICLR 2022 Ziniu Li, Yingru Li, Yushun Zhang, Tong Zhang, Zhi-Quan Luo

However, it is limited to the case where 1) a good feature is known in advance and 2) this feature is fixed during the training: if otherwise, RLSVI suffers an unbearable computational burden to obtain the posterior samples of the parameter in the $Q$-value function.
