| Abstract: | The prediction of Eukaryotic promoter is one of the most important problems in DNA sequence analysis. In this work, we develop a new algorithm which is based on word considering the double-stranded characteristics of DNA. The frequency of occurrence of characteristics is represented by positional weight matrix. The boosting algorithm is used to train and predict respectively. The results in the algorithms have better sensitivity and specificity than that of the other algorithms. |
