Then we introduced transition probability kernel for the hidden state process and the confederated process. In the deep research, we found that some similar parameters of state transition probability, observation symbol probability and initial state probability were involved in the transition probability kernel of the confederated process. So we can complete the training of traditional HMM parameters by training the transition probability kernel of the confederated process. To our surprised, we got the consistency of transition probability kernel of the confederated process. Meanwhile, we proved the rationality and reliability of the parameters estimation equations under the classical B-W algorithm.
然后对联合过程的转移概率核展开研究,我们根据过程的取值空间的不同,引入了隐状态空间和联合过程空间上的转移概率核,研究中发现在联合空间上的转移概率核包含了在一般的隐马氏模型的参数估计中的所有类似的三组参数(转移概率,观测概率和初始概率),因此对传统的隐马氏模型的参数训练我们可以通过联合过程的转移概率核的训练来完成,更令我们惊奇的是联合过程的转移概率核还具有一致性;同时对于Baum提出的经典的B-W算法给出的关于模型的参数重估计公式,证明了它的合理性和可靠性,即模型经过重估计后的参数能够满足给定的单观测序列在模型下发生的概率是单调递增的。
