Planning with World Models and Learned Temporal Abstractions


Scalable Decision-Making in Stochastic Environments through Learned Temporal Abstraction

Published in The Thirteenth International Conference on Learning Representations (ICLR 2025), 2025 Spotlight (top 5.1%)

This paper introduces the Latent Macro Action Planner (L-MAP), which learns temporally extended macro-actions with a state-conditioned VQ-VAE and plans over them with Monte Carlo Tree Search, enabling low-latency decision-making in stochastic, high-dimensional continuous control.
