Estimating the parameters of Markov model using entropic function as a criterion
HU Bi-jin · Journal of Chongqing Jiaotong University · 2006
Markov model plays an important role in the recognition field of standard text and hand-writing.In order to consider how to reestimate model-parameters from observation data,the criterion function introduced by the entropic properties of the model replaces Baum auxiliary function,and formulas of reestimating model-parameters is obtained using the properties of the criterion function introduced by the entropic properties of the model.
