Reusing Historical Trajectories in Natural Policy Gradient via Importance Sampling: Convergence and Convergence Rate

no code implementations1 Mar 2024 Yifan Lin, Yuhao Wang, Enlu Zhou

The efficient utilization of historical trajectories obtained from previous policies is essential for expediting policy optimization.

Approximate Bilevel Difference Convex Programming for Bayesian Risk Markov Decision Processes

no code implementations26 Jan 2023 Yifan Lin, Enlu Zhou

We consider infinite-horizon Markov Decision Processes where parameters, such as transition probabilities, are unknown and estimated from data.

Risk-averse Contextual Multi-armed Bandit Problem with Linear Payoffs

no code implementations24 Jun 2022 Yifan Lin, Yuhao Wang, Enlu Zhou

In particular, we consider mean-variance as the risk criterion, and the best arm is the one with the largest mean-variance reward.

Design of optical voltage sensor based on electric field regulation and rotating isomerism electrode

no code implementations14 Jun 2022 Jun Li, Yifan Lin, Nan Xie

This technology could shift the measured signal frequency band from near 50 Hz moved to several kilometer Hz, so as to make the output signal avoid the interference from low-frequency temperature drift, stress birefringence and vibration, leading to higher stability and reliability.
