Combining multiple hypothesis testing and affinity propagation clustering leads to accurate robust and sample size independent classification on gene expression data

摘要

BackgroundA feature selection method in microarray gene expression data should be independent of platform, disease and dataset size. Our hypothesis is that among the statistically significant ranked genes in a gene list, there should be clusters of genes that share similar biological functions related to the investigated disease. Thus, instead of keeping N top ranked genes, it would be more appropriate to define and keep a number of gene cluster exemplars.
