| Abstract: | Hidden Markov models(HMMs)are statistical models of sequential data that have been used successfully in many machine learning applications,especially in protein family recognition in the last few years.This is due to the vast increase of data in biology that makes two fields(computational science and biology)associate with each other. To study multiple sequence alignment and profile HMMs,one essential algorithm of HMMs and how to build an HMMs are discussed.By E values and training scores an experiment for recognition and classification of protein family is given. |
