Hierarchical actor critic

Web1 de abr. de 2006 · Abstract. We consider the problem of control of hierarchical Markov decision processes and develop a simulation based two-timescale actor-critic algorithm in a general framework. We also develop certain approximation algorithms that require less computation and satisfy a performance bound. One of the approximation algorithms is a … Web4 de dez. de 2024 · We present a novel approach to hierarchical reinforcement learning called Hierarchical Actor-Critic (HAC). HAC aims to make learning tasks with sparse binary rewards more efficient by enabling agents to learn how to break down tasks from scratch. The technique uses of a set of actor-critic networks that learn to decompose …
