The Baum-Welch algorithm of mixture of HMM2

摘要: 介绍了在观测噪声和马尔可夫链不相互独立的条件下混合二阶隐马尔可夫模型(HMM2)的结构.然后,研究了新模型的Baum-Welch算法,并导出了新模型的参数估计公式.

Abstract: It is first described that the structure of mixture of HMM2 on condition that observation noise is not independent of the Markov chain,and then the Baum-Welch algorithm of new model and derive the update parametric estimation equations for the new model are researched.
