Clusters produced by Block PCA and K-means. In (A), 30 points are randomly generated on a plane. Three clusters calculated by K-means are shown in (B). The low rank matrix calculated by the splitting algorithm is depicted in (C). The corresponding three clusters calculated by SSVD are displayed with different colors depicted in (D). Among 30 data points, two points (the point 25 and 30) are outliers, not included in any cluster. The clustering result of the remaining 28 points is identical with that of K-means.
