cDNA生物芯片表达数据广泛用于生物医学研究,利用计算机对其进行处理还有很多挑战性课题。该文提出了一种新的基于不变基因的多类生物芯片监督型集合cDNA表达数据标准化方法。在达到标准化的同时,该方法也可直接用于基因表达数据的特征选择,实验证明效果较好。 cDNA biochip expression data is widely used in biomedical research and there are many challenging topics for using computer to process it. In this paper, we propose a new standardized method based on invariant genes for supervised collection of cDNA expression data from a variety of biochips. While achieving the standardization, this method can also be directly used for the feature selection of gene expression data, the experiment proves that the effect is better.
