| 摘 要： | 针对基因表达谱数据特有的维数高、样本小、非线性的特点,对基因特征提取和分类进行研究,提出将Logistic回归和T检验方法引入基因的特征提取过程,通过Logistic回归初步筛选基因,T-test检验二次筛选特征基因,针对提取的特征构建分类器,得到提取的特征最少、分类效果最好的判别模型.建立分类模型的方法取得良好的癌症分类效果,具有很好的生物解释意义,为寻找致病基因提供了重要依据.

| Abstract: | Based on the research of gene feature extraction andits classification,this paper introduces the Logistic regression and T test method into gene feature extraction process.Specifically,through the Logistic regression preliminary selecting in gene,T-test inspection secondary screening genetic characteristics,and finally building classifier according to the extracted characteristics,this paper comes to a conclusion with the best discriminatory analysis under which the extracted characteristics is least,but classification effect is the best. |
