In this post, I will illustrate Markov Property, Markov Reward Process and finally Markov Decision Process, which are fundamental concepts in Reinforcement Learning. Markov Property 'The state is independent of the past given the present' Markov Proc…
From the last post about MDP, we know the environment consists of 5 basic elements: S:State Space of environment; A:Actions Space that the environment allows; {Ps,s'}:Transition Matrix, the probabilities of how environment state transit from one to a…

机器学习中的隐马尔科夫模型(HMM)详解 在之前介绍贝叶斯网络的博文中,我们已经讨论过概率图模型(PGM)的概念了.Russell等在文献[1]中指出:"在统计学中,图模型这个术语指包含贝叶斯网络在内的比较宽泛的一类数据结构." 维基百科中更准确地给出了PGM的定义:"A graphical model or probabilistic graphical model is a probabilistic model for which a graph expresses t…

We have seen that directed graphical models specify a factorization of the joint distribution over a set of variables into a product of local conditional distributions. They also define a set of conditional independence properties that must be satisf…
