Equivariant Data Augmentation for Generalization in Offline Reinforcement Learning

no code implementations14 Sep 2023 Cristina Pinneri, Sarah Bechtle, Markus Wulfmeier, Arunkumar Byravan, Jingwei Zhang, William F. Whitney, Martin Riedmiller

We present a novel approach to address the challenge of generalization in offline reinforcement learning (RL), where the agent learns from a fixed dataset without any additional interaction with the environment.

Multi-Modal Learning of Keypoint Predictive Models for Visual Object Manipulation

no code implementations8 Nov 2020 Sarah Bechtle, Neha Das, Franziska Meier

Our evaluation shows that our approach learns to consistently predict visual keypoints on objects in the manipulator's hand, and thus can easily facilitate learning an extended kinematic chain to include the object grasped in various configurations, from a few seconds of visual data.

Curious iLQR: Resolving Uncertainty in Model-based RL

no code implementations15 Apr 2019 Sarah Bechtle, Yixin Lin, Akshara Rai, Ludovic Righetti, Franziska Meier

In this work, we propose a model-based reinforcement learning (MBRL) framework that combines Bayesian modeling of the system dynamics with curious iLQR, an iterative LQR approach that considers model uncertainty.
