METHODS: A six state (Wake, S1, S2, S3, S4 and REM) Markov state transition sleep model was built. Transition probabilities between states were calculated with autoregressive multinomial logistic regression based on polysomnographic laboratory study data. Monte Carlo simulation trials were performed ...

然后我们规定,一个Policy Π 是一个state到一个action的映射,比如说: Π(s)= walk, 如果s是奇数, Π(s)= dice, 如果s是偶数,但不是20, Π(s)= nil, 如果s=20, 注意把policy和transition probabilities区别开来,前者相当于是一种规定,后者是概率,涉及到计算问题。特别的,T(s, nil, s’) =1, rewar...
State 1 is the low-variance state. The full set of transition probabilities is the following: from/to state1 2 10.76 1 - 0.76 20.15 1 - 0.15 As in the previous model, the states are persistent. mswitchhas other features such as calculating smoother transitions using autoregressive models. ...

注意一个含有 N 个状态的一阶过程有 N2个状态转移。每一个转移的概率叫做状态转移概率(state transition probability),就是从一个状态转移到另一个状态的概率。这所有的 N2个概率可以用一个状态转移矩阵来表示,其表示形式如下: 对该矩阵有如下约束条件: ...
the state transition matrix; the confusion matrix; 这其中,所有的状态转移概率和混淆概率在整个系统中都是一成不变的。这也是HMM中最不切实际的假设。 HMM的应用 有三个主要的应用:前两个是模式识别后一个作为参数估计 (1) 评估 根据已知的HMM找出一个观察序列的概率。
This transition rate matrix yields a Markov State Model of the molecular dynamics. We use Perron cluster analysis and coarse-graining techniques in order to identify metastable sets in configuration space and approximate the transition rates between the metastable sets. Application of our method to a...
