Abstract: In order to improve identification accuracy of splice site, a novel splice sites identification model is proposed based on Multi-Scale Component features and Adjacent Positions Relationship features（MSC-APR）. The window length of splice site conservation sequence is determined, and then multi-scale component and adjacent positions relationship features are extracted, features are combined and are input into least squares support vector machine to learn and establish the classifier of splice sites, and the data of HS3D and NN269 are used to test the performance of model. The experimental results show that compared with the other models, the proposed model has obtained higher identification accuracy of splice sites and superiority to other models.
