BayesContact: Uncertain Pose Estimation via Visuo-Tactile Proposals and Simulation-based Inference

Aditya Kamireddypalli, Matias Mattamala, Joao Moura, Russell Buchanan, Sethu Vijayakumar, Subramanian Ramamoorthy

Contact-rich manipulation requires pose estimates that are often more accurate than what depth-only sensing provides. Existing methods, relying on vision and contact, employ costly offline training procedures that need to be retrained for new environments and geometries. We propo…

RENEW: Towards Learning World Models and Repairing Model Exploitation from Preferences

Logan Mondal Bhamidipaty, Mykel Kochenderfer, Subramanian Ramamoorthy

World models are widely used in offline reinforcement learning (RL) to improve sample efficiency and generate experience beyond a fixed dataset. However, they are vulnerable to model exploitation where data coverage is thin. Prior work addresses this either by collecting more exp…
