摘要
隐马尔可夫模型(Hidden Markov Model,HMM)的基本算法体系主要包括Baum-Welch算法、前向-后向算法与Viterbi算法三大经典算法,通过展开对HMM新问题及新算法的理论研究,引出逆维特比问题及逆维特比算法的理论体系,并提出将逆维特比算法引入HMM基本算法体系中构建一种新的算法体系及一种新评估体系的构想,最后对新算法体系的应用进行了展望。
The system of the basic Hidden Markov Model (HMM) algorithm includes the three important algorithms of Baum-Welch algorithm, Forward-Backward algorithm and Viterbi algorithm. The Inv-viterbi problem and its corresponding algorithm is put forward in the paper after the research of the new HMM problem and algorithm. Then a new algorithm system and a new evaluation system are built by introducing the Inv-viterbi algorithm into the HMM basic algorithm system. Finally we give a prospect on the application of the new algorithm system.
