K-means c-means
Webkmeans A simple C routine for generic K-means calculations. All the K-means code I found was either too complex, or bound to assumptions about 2-dimensionality, or n-dimensionality, and I really just wanted something … WebIf a callable is passed, it should take arguments X, n_clusters and a random state and return an initialization. n_init‘auto’ or int, default=10. Number of time the k-means algorithm will be run with different centroid seeds. The final results will be the best output of n_init consecutive runs in terms of inertia.

WebIn data mining, k-means++ is an algorithm for choosing the initial values (or "seeds") for the k-means clustering algorithm. It was proposed in 2007 by David Arthur and Sergei Vassilvitskii, as an approximation algorithm for the NP-hard k-means problem—a way of avoiding the sometimes poor clusterings found by the standard k-means algorithm.It is …
