Improving Policy Learning from Delayed Interventions

Xiru Zhu, David Meger, Gregory Dudek

In this work, we explore the idea of expert intervention delays in human-supervised robotic systems for imitation learning system. Previous works in imitation learning have primari…

Convergence Theorems for Entropy-Regularized and Distributional Reinforcement Learning

Yash Jhaveri, Harley Wiltzer, Patrick Shafto +2

In the pursuit of finding an optimal policy, reinforcement learning (RL) methods generally ignore the properties of learned policies apart from their expected return. Thus, even wh…

Large Pre-Trained Models for Bimanual Manipulation in 3D

Hanna Yurchyk, Wei-Di Chang, Gregory Dudek +1

We investigate the integration of attention maps from a pre-trained Vision Transformer into voxel representations to enhance bimanual robotic manipulation. Specifically, we extract…

EMoE: Training-Free Expert Disagreement for Uncertainty-Aware Text-to-Image Diffusion

Lucas Berry, Axel Brando, Wei-Di Chang +2

Large text-to-image diffusion models rarely expose reliable signals of when a prompt is likely to produce a poorly aligned generation, especially when training data is undisclosed.…

Tractable Representations for Convergent Approximation of Distributional HJB Equations

Julie Alhosh, Harley Wiltzer, David Meger

In reinforcement learning (RL), the long-term behavior of decision-making policies is evaluated based on their average returns. Distributional RL has emerged, presenting techniques…

Fairness in Reinforcement Learning with Bisimulation Metrics

Sahand Rezaei-Shoshtari, Hanna Yurchyk, Scott Fujimoto +2

Ensuring long-term fairness is crucial when developing automated decision making systems, specifically in dynamic and sequential environments. By maximizing their reward without co…
