HMM是一个双重随机过程---具有一定状态的隐马尔可夫链(天气情况)和随机的观测序列(地面潮湿情况)。 The HMM is a discrete time model: for each point in time t, we have one hidden state that generates one observed event for that time point t. HMM HMM应用条件 The hidden states follow a Markov ...
Hidden Markov ModelbioinformaticsMultiple criteria decision making (MCDM) has significant impact in bioinformatics. In the research reported here, we explore the integration of decision tree (DT) and Hidden Markov Model (HMM) for subtype prediction of human influenza A virus. Infection with influenza ...

1、MM,Markov model 马尔科夫模型 (1)天气举例 假设只有晴、阴、雨三种天气情况。某地周一为晴天,已知若晴天后,第二天出现晴阴雨的概率分别为0.5,0.3,0.2(sum=1)。 例如周二为雨天的概率即为0.2。而已知若雨天后,第二天出现晴阴雨的概率分别为0.1,0.6,0.3(sum=1),可预测周三为阴天的概率为0.2*0.3=0.06。

the hidden Markov model attempts to predict the future state of a variable using probabilities based on the current and past state. The key difference between a Markov chain and the hidden Markov model is that the state in the latter is not directly visible to an observer, even though the ...
