核心概念
Hierarchical RL methods like COInS use interaction-guided skill discovery to improve sample efficiency and transferability in complex tasks.
摘要
The article introduces the Chain of Interaction Skills (COInS) algorithm for hierarchical skill discovery in reinforcement learning.
COInS focuses on controllability in factored domains to identify task-agnostic skills that permit a high degree of control.
The algorithm uses Granger-causal tests to detect interactions between state factors and trains a chain of skills to control each factor successively.
Evaluation on a robotic pushing task with obstacles shows significant improvement in sample efficiency and final performance compared to standard RL baselines.
COInS breaks down complex tasks into transferable, intuitive skills automatically, improving sample efficiency by reducing the time horizon through skill learning.
Abstract
Reinforcement Learning (RL) has shown promise but struggles with high data requirements and brittle generalization.
Hierarchical RL methods aim to address these limitations by decomposing policies into skills and reusing them across different tasks.
COInS algorithm focuses on controllability in factored domains using Granger-causal tests to detect interactions between state factors.
