基本概念 样本空间: 随机试验E的所有可能结果组成的集合, 为E的样本空间, 记为S 随机事件: E的样本空间S的子集为E的随机事件, 简称事件, 由一个样本点组成的单点集, 称为基本事件 对立事件/逆事件: 若A并B=S, 且A交B=空, 则称A与B互为逆事件, A与B互为对立事件. A上面加一横即A的逆事件 频率: 在相同的条件下进行了n次试验, 事件A发生的次数为A的频数, 与n的比值成为A的频率 概率: 设E为随机试验, S是E的样本空间, 对于E的每一个事件A赋予一个实数, 记为P(A…

郑重声明:原文参见标题,如有侵权,请联系作者,将会撤销发布! arXiv:1902.08102v1 [stat.ML] 21 Feb 2019 Abstract 我们通过递归估计回报分布的统计量,提供了一个统一的框架,用于设计和分析分布强化学习(DRL)算法.我们的主要见识在于,可以将DRL算法分解为一些统计量估计和一种方法的组合,该方法插补与该统计集一致的回报分布.有了这种新的理解,我们就能对现有DRL算法进行改进的分析,并基于对回报分布期望的估计来构造新的算法(EDRL).我们将EDRL与各…
