二维隐马氏模型的一种简化算法及其参数估计

An Abridged Algorithm and Parameter Estimation of Two Dimension Hidden Markov Chain Model

针对现有的二维隐马氏模型算法给出了一种简化算法及参数估计方法。该算法与现有的算法相比非常简单。基于此方法给出了相应的识别方法和参数估计,并且该估计与极大似然估计是等同的。

An abridged algorithm of 2D hidden Markov chain model and its parameter estimation method are made. This method is simplier compared with preceding ones. Based on this method the corresponding recognition method and parameter estimation are presented. And estimating parameters in this manner is equivalent to the maximizing of the likelihood.
