Unifying Model-Free Efficiency and Model-Based Representations via Latent Dynamics
A research paper introduces Unified Latent Dynamics (ULD), a new reinforcement learning algorithm designed to combine the efficiency of model-free methods with the representational power of model-based approaches. ULD achieves this by embedding state-action pairs into a latent space where the value function is approximately linear, thereby avoiding the computational overhead of planning. The algorithm has demonstrated strong performance across a variety of domains, including continuous control and Atari games, matching or surpassing specialized baselines with fewer parameters and minimal tuning.
