武警部长依据你的方法,召集手下人员,很快就得出了那犯罪团伙的防卫状况以及其他信息。在几天后的精密策划的抓捕行动中,犯罪团伙成员悉数落网。大家听了你的故事后,都对你很是敬佩,武警部长更是高兴,对你连声称赞。几天后一个晚上,武警部长悄悄找到你,对你说:“鲍姆-韦尔奇算法Baum–Welch algorithm这么神奇。但,你...

We estimate transition and emission probabilities of the model only based on sequences containing CpG islands without known keys. We use the Baum Welch algorithm, which is a special case of the EM (expectation maximization) algorithm. It makes use of the forward-backward algorithm to compute the...
Parameters of the model are redefined through the Baum Welch algorithm and the maximum probability state transition sequence is further calculated by using the Viterbi algorithm. Based on these processes, the intention of attackers has been finally inferred. According to the experimental results, the ...

Baum-Welch algorithm, which is often troubled with overflow, is one of the basic methods in the field of speech signal processing. People have to adjust the inner parameters constantly. So in this paper, a modified Baum-Welch algorithm is presented to avoid the overflow completely. With this ...
