A diﬀerent approach is the mini batch K-means algorithm ([11]). Its main idea is to use small random batches of examples of a ﬁxed size so they can be stored in memory. WebA demo of the K Means clustering algorithm ¶ We want to compare the performance of the MiniBatchKMeans and KMeans: the MiniBatchKMeans is faster, but gives slightly different results (see Mini Batch K-Means ). We will cluster a set of data, first with KMeans and then with MiniBatchKMeans, and plot the results.
