Policy Learning based on Deep Koopman Representation

no code implementations24 May 2023 Wenjian Hao, Paulo C. Heredia, Bowen Huang, Zehui Lu, Zihao Liang, Shaoshuai Mou

This paper proposes a policy learning algorithm based on the Koopman operator theory and policy gradient approach, which seeks to approximate an unknown dynamical system and search for optimal policy simultaneously, using the observations gathered through interaction with the environment.

A Data-Driven Approach for Inverse Optimal Control

no code implementations31 Mar 2023 Zihao Liang, Wenjian Hao, Shaoshuai Mou

By assuming the objective function to be learned is parameterized as a linear combination of features with unknown weights, the proposed approach for IOC is able to achieve a Koopman representation of the unknown dynamics and the unknown weights in objective function together.

Deep Koopman Learning of Nonlinear Time-Varying Systems

no code implementations12 Oct 2022 Wenjian Hao, Bowen Huang, Wei Pan, Di wu, Shaoshuai Mou

This paper presents a data-driven approach to approximate the dynamics of a nonlinear time-varying system (NTVS) by a linear time-varying system (LTVS), which is resulted from the Koopman operator and deep neural networks.
