Entropy-regularized Diffusion Policy with Q-Ensembles for Offline Reinforcement Learning

1 code implementation6 Feb 2024 Ruoqi Zhang, Ziwei Luo, Jens Sjölund, Thomas B. Schön, Per Mattsson

We show that such an SDE has a solution that we can use to calculate the log probability of the policy, yielding an entropy regularizer that improves the exploration of offline datasets.

Aiding reinforcement learning for set point control

no code implementations20 Apr 2023 Ruoqi Zhang, Per Mattsson, Torbjörn Wigren

While reinforcement learning has made great improvements, state-of-the-art algorithms can still struggle with seemingly simple set-point feedback control problems.

Robust nonlinear set-point control with reinforcement learning

no code implementations20 Apr 2023 Ruoqi Zhang, Per Mattsson, Torbjörn Wigren

This paper argues that three ideas can improve reinforcement learning methods even for highly nonlinear set-point control problems: 1) Make use of a prior feedback controller to aid amplitude exploration.

Observer-Feedback-Feedforward Controller Structures in Reinforcement Learning

no code implementations20 Apr 2023 Ruoqi Zhang, Per Mattson, Torbjörn Wigren

As discussed in the paper, this leads to a separation of the observer dynamics to the recurrent neural network part, and the state feedback to the feedback and feedforward network.
