| Abstract: | FMC clustering is used for gene expression data, a combination of kernel regression and projection pursuit regression introduced into the design of predictors, and coefficient of determination used as a criterion in selecting the target gene's parent sets. Comparisons between the results based on the proposed method and those in the literature indicate the advantage of the proposed algorithms. The combination-design methods are recommended in finding and analyzing the carcinogenic genes clusters of human cancer. |
