Code as Reward: Empowering Reinforcement Learning with VLMs

no code implementations7 Feb 2024 David Venuto, Sami Nur Islam, Martin Klissarov, Doina Precup, Sherry Yang, Ankit Anand

Pre-trained Vision-Language Models (VLMs) are able to understand visual concepts, describe and decompose complex tasks into sub-tasks, and provide feedback on task completion.

Policy Gradients Incorporating the Future

no code implementations ICLR 2022 David Venuto, Elaine Lau, Doina Precup, Ofir Nachum

Reasoning about the future -- understanding how decisions in the present time affect outcomes in the future -- is one of the central challenges for reinforcement learning (RL), especially in highly-stochastic or partially observable environments.
