Abstract

The gene structure is consist of intron, exons, promoter, start codon, stop codon, etc. for the eukaryotic organism. The boundary between intron and exon is splice site. There is the need for accurate algorithms to be used in the splice sites identification and more attention was paid during past few years. This proposed system, Splice Hybrid have three layered architecture — in this layer2nd orderMM is used in the initial stage, i.e. feature extraction; intermediate stage for feature selection principal feature analysis is used; and in the final layer a SVM with RBF kernel is used. In comparison Splice Hybrid tool gives better performance.
剪接位点预测的杂交技术
真核生物的基因结构由内含子、外显子、启动子、起始密码子、终止密码子等组成。内含子和外显子的边界是剪接位点。在剪接位点的识别中需要使用精确的算法,近年来受到越来越多的关注。Splice Hybrid系统采用三层结构,在该结构中,在初始阶段,即特征提取阶段,使用第二层orderMM;中间阶段为特征选择阶段,主要进行特征分析;最后一层采用带RBF核的支持向量机。相比之下,Splice Hybrid工具提供了更好的性能。
