See also KMeans Web3. Compare BIRCH and MiniBatchKMeans. This example compares the timing of Birch (with and without the global clustering step) and MiniBatchKMeans on a synthetic dataset having 100,000 samples and 2 features generated using make_blobs. If n_clusters is set to None, the data is reduced from 100,000 samples to a set of 158 clusters.
