PPT-Lloyd Algorithm K-Means Clustering

Gene Expression Susumu Ohno whole genome duplications The expression of genes can be measured over time Identifying which genes are expressed at a given moment can help determine function Grouping. x and want to group the data into a few cohesive clusters Here as usual but no labels are given So this is an unsupervised learning problem The means clustering algorithm is as follows 1 Initialize cluster centroids 57525 57525 randomly 2 Repeat u Machine .
