WebOct 14, 2024 · x2 : x0. Looking at the x2 : x0 projection, the dataset looks like as if it only had two clusters. The lower-right “supercluster” is, in fact, two distinct groups and even if we guess K right (K = 3), it looks like an apparent error, despite the clusters are very localized. Figure 3a. Projection on `x0 : x2` shows spurious result ( compare ... WebNov 5, 2024 · The k-means algorithm divides a set of N samples X into K disjoint clusters C, each described by the mean μj of the samples in the cluster. The means are commonly called the cluster “centroids”; note that they are not, in general, points from X, although they live in the same space. The K-means algorithm aims to choose centroids that ...
