WebHierarchical Actor-Critic is an algorithm that enables agents to learn from experience how to break down tasks into simpler subtasks. Similar to the traditional actor-critic approach used in goal-based learning, the ultimate aim is to find a robust policy function that maps from the state and goal space to the action space.
