On-Policy v/s Off-Policy Learning - Towards Data Science
Web24 de mar. de 2024 · 5. Off-policy Methods. Off-policy methods offer a different solution to the exploration vs. exploitation problem. While on-Policy algorithms try to improve the … 前面提到off-policy的特点是:the learning is from the data off the target policy,那么on-policy的特点就是:the target and the behavior polices are the same。也就是说on-policy里面只有一种策略,它既为目标策略又为行为策略。SARSA算法即为典型的on-policy的算法,下图所示为SARSA的算法示意图,可以看出算法 … Ver mais 抛开RL算法的细节,几乎所有RL算法可以抽象成如下的形式: RL算法中都需要做两件事:(1)收集数据(Data Collection):与环境交互,收集学习样 … Ver mais RL算法中的策略分为确定性(Deterministic)策略与随机性(Stochastic)策略: 1. 确定性策略\pi(s)为一个将状态空间\mathcal{S}映射到动作空间\mathcal{A}的函数,即\pi:\mathcal{S}\rightarrow\mathcal{A} … Ver mais (本文尝试另一种解释的思路,先绕过on-policy方法,直接介绍off-policy方法。) RL算法中需要带有随机性的策略对环境进行探索获取学习样本,一种视角是:off-policy的方法将收集数 … Ver mais easy english riddles
