By applying the Kmeans to reordering data, and applying original Cheng and Church algorithm to get biclusters. Our proposed model improve the accuracy score and run time of algorithm. We verified this new model proposed with many variant synthetic datasets and calculate the score of three external evaluation measures: Relative NonIntersecting Area (RNIA) and Clustering Error (CE), Campello Soft Index (CSI).enCheng and Church, KMEANS, Biclustering, DNA Microarray, Gene Expression, Clustering.Thesis
