Learning Predictive Safety Filter via Decomposition of Robust Invariant Set

no code implementations12 Nov 2023 Zeyang Li, Chuxiong Hu, WeiYe Zhao, Changliu Liu

This paper presents a theoretical framework that bridges the advantages of both RMPC and RL to synthesize safety filters for nonlinear systems with state- and action-dependent uncertainty.

Bridging the Gap between Newton-Raphson Method and Regularized Policy Iteration

no code implementations11 Oct 2023 Zeyang Li, Chuxiong Hu, Yunan Wang, Guojian Zhan, Jie Li, Shengbo Eben Li

We also show that a modified version of regularized policy iteration, i. e., with finite-step policy evaluation, is equivalent to inexact Newton method where the Newton iteration formula is solved with truncated iterations.

Real-time detection of abnormal driving behavior based on long short-term memory network and regression residuals

no code implementations Transportation Research Part C: Emerging Technologies 2022 Yongfeng Ma, Zhuopeng Xie, Shuyan Chen, Fengxiang Qiao, Zeyang Li

Second, a time windowbased residual algorithm is designed and employed to detect abnormal driving behavior according to the magnitude and continuity of the residuals.

Smoothing Policy Iteration for Zero-sum Markov Games

no code implementations3 Dec 2022 Yangang Ren, Yao Lyu, Wenxuan Wang, Shengbo Eben Li, Zeyang Li, Jingliang Duan

In this paper, we propose the smoothing policy iteration (SPI) algorithm to solve the zero-sum MGs approximately, where the maximum operator is replaced by the weighted LogSumExp (WLSE) function to obtain the nearly optimal equilibrium policies.

Scalable Quantum Tomography with Fidelity Estimation

1 code implementation8 Dec 2017 Jun Wang, Zhao-Yu Han, Song-Bo Wang, Zeyang Li, Liang-Zhu Mu, Heng Fan, Lei Wang

We propose a quantum tomography scheme for pure qudit systems which adopts random base measurements and generative learning methods, along with a built-in fidelity estimation approach to assess the reliability of the tomographic states.
