5. Consider a gene expression profiling matrix shown in the table below where the expression measurements of two genes in five samples are recorded. Sample S1 Gene 1 Gene 2 Class label 10 5 P S2 12 3 P S3 20 10 - S4 22 S5 18 12 8 N N Assume that S1, S2, and S3 are initially assigned in one cluster and S4 and S5 in another cluster. Apply the k-means method to cluster the five samples into two clusters. Show the detailed workings.
