WebDec 14, 2013 · K-means pushes towards, kind of, spherical clusters of the same size. I say kind of because the divisions are more like voronoi cells. From here that in the first example you would end up with overlapped clusters. There are clearly three clusters, a big one and two small ones. WebOne way to quickly visualize whether high dimensional data exhibits enough clustering is to use t-Distributed Stochastic Neighbor Embedding . It projects the data to some low dimensional space (e.g. 2D, 3D) and does a pretty good job at keeping cluster structure if any. E.g. MNIST data set: Olivetti faces data set: how lifts work video
