Zero-Shot Wireless Indoor Navigation through Physics-Informed Reinforcement Learning

1 code implementation11 Jun 2023 Mingsheng Yin, Tao Li, Haozhe Lei, Yaqi Hu, Sundeep Rangan, Quanyan Zhu

To equip the navigation agent with sample-efficient learning and {zero-shot} generalization, this work proposes a novel physics-informed RL (PIRL) where a distance-to-target-based cost (standard in e2e) is augmented with physics-informed reward shaping.

Sampling Attacks on Meta Reinforcement Learning: A Minimax Formulation and Complexity Analysis

1 code implementation29 Jul 2022 Tao Li, Haozhe Lei, Quanyan Zhu

It leads to two online attack schemes: Intermittent Attack and Persistent Attack, which enable the attacker to learn an optimal sampling attack, defined by an $\epsilon$-first-order stationary point, within $\mathcal{O}(\epsilon^{-2})$ iterations.
