Abstract
Cluster analysis has been widely used to explore thousands of gene expressions from microarray analysis and identify a small number of similar genes objects for further detailed biological investigation However most clustering algorithms tend to identify loose clusters with too many genes In this paper we propose a Bayesian tight clustering method for time course gene expression data which selects a small number of closelyrelated genes and constructs tight clusters only with these closelyrelated genes
