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…

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…

Dictum:  Is the true wisdom fortitude ambition. -- Napoleon 马尔可夫决策过程(Markov Decision Processes, MDPs)是一种对序列决策问题的解决工具,在这种问题中,决策者以序列方式与环境交互. "智能体-环境"交互的过程 首先,将MDPs引入强化学习.我们可以将智能体和环境的交互过程看成关于离散情况下时间步长\(t(t=0,1,2,3,\ldots)\)的序列:\(S_0,A_0,R_1,S_1,A_1…

Learning to Track: Online Multi-Object Tracking by Decision Making ICCV   2015 本文主要是研究多目标跟踪,而 online 的多目标检测的主要挑战是 如何有效的将当前帧检测出来的目标和之前跟踪出来的目标进行联系.本文将 online MOT problem 看做是 MDPs 问题,用一个 MDP 来建模一个物体的生命周期.学习物体相似性的度量 就等价于学习MDP的一个策略,而该策略的学习可以用RL 的方式进行,能够兼顾…

一.前言 在第一章强化学习简介中,我们提到强化学习过程可以看做一系列的state.reward.action的组合.本章我们将要介绍马尔科夫决策过程(Markov Decision Processes)用于后续的强化学习研究中. 二.马尔科夫过程(Markov Processes) 2.1 马尔科夫性 首先,我们需要了解什么是马尔科夫性: 当我们处于状态StSt时,下一时刻的状态St+1St+1可以由当前状态决定,而不需要考虑历史状态. 未来独立于过去,仅仅于现在有关 将从状态s 转移到状态 s…
