Research on EM Algorithm and Its Application in Text Processing
Introduces the current situation of the development of today,text processing,and introduces EM iterative algorithm for the classic one,and the derivation of the EM algorithm,and the specific implementation steps of algorithm of poly a further description;then after the summary of several methods commonly used nowadays in text classification,focuses on the analysis of Bayes classification methods,and the combination of EM and Bayes algorithm,application of enhanced Bayes classifier in text processing and text classification,indirectly,to improve the classification accuracy of Bayes,and describes the deficiencies in the face of the future data times how to compensate for the EM algorithm.
