ProDVI: Programmatic Dynamics Priors for Value Network Initialization

ProDVI is a framework that leverages the commonsense and domain knowledge encoded in large language models to initialize RL agents without relying on these resources and can effectively improve the sample efficiency of model-free RL algorithms.

Observation-Grounded Self-Predictive Reinforcement Learning for Visual Continuous Control

Observation-Grounded Self-Predictive Representations (OG-SPR), a model-free visual RL algorithm for continuous control that learns representations that are both temporally predictive in latent space and grounded in observation-level dynamics, is proposed.
