TRANSCRIPTION FACTOR BINDING SITES RECOGNITION BASED ON MULTIPLE DATA DOMAIN DESCRIPTION
摘要
Abstract
Transcription factor binding site recognition plays an important role in the comprehension of transcription regulation mechanism,and is the great challenge the post-genome era encounters as well. In this paper we present a multi-task learning based approach for the problem of transcription factor binding sites (TFBS) recognition. Firstly, a new multiple data domain description model was established, it was based on the theory of multi-task learning; then in combination with kernel methods, a multiple classification recognition algorithm for transcription factor binding site was designed. Finally,the real data set retrieved from TRANSFAC database was tested with cross-validation.Experimental result indicated that this approach can fully use scarce training samples and effectually capture the inter-class relations ,therefore attained quite high accuracy in prediction.关键词
