Recognizing genes with distinctive expression levels can help in prevention, diagnosis and treatment of the diseases at the genomic level. In this paper, fast Global k-means (fast GKM) is developed for clustering the gene expression datasets. Fast GKM is a significant improvement of the k-means clustering method. It is an incremental clustering method which starts with one cluster. Iteratively ...

dna microarray is a powerful approach to study simultaneously, the expression of 1000 of genes in a single experiment. the average value of the fluorescent intensity could be calculated in a microarray experiment. the calculated intensity values are very close in amount to the levels of expression of a particular gene. however, determining the appropriate position of every spot in microarray im...
