Researchers have introduced HaM-World, a novel structured world model designed to improve the stability and accuracy of planning in reinforcement learning. This model decomposes latent states into canonical (q, p) and context (c) subspaces, incorporating Mamba selective state-space memory to handle history-conditioned inputs. HaM-World utilizes a soft-Hamiltonian vector field for dynamics prediction, demonstrating superior performance on DeepMind Control Suite tasks and enhanced robustness against out-of-distribution perturbations.
