摘要
提出一种基于遗传算法的数据挖掘方法——TGASVM,它能够尽可能少地选出分类能力强的信息基因.实验表明与同类的算法相比,TGASVM算法无论是分类准确率,还是挑选信息基因数目都优于同类算法.
Gene expression profiles is a high - throughput data. However, only a small number of gene mutations related to tumor development. So,it is a huge challenge that design good algorithms to discover information Genes from microarray data. In this paper,we presented a data mining method named TGASVM (Test Genetic Algorithms Support Vector Machine), which as little as possible to elect information genes , however, which have a good classification ability based on SVM. Compared with other similar algorithms, both classification of TCGASVM the accuracy and the number of information genes of TCGASVM are better.
