[PYTHON] kmeans ++ with scikit-learn

Motivation

I want to use kmeans ++ in my own clustering method. There is kmeans ++ in the initialization method of sklearn.cluster.KMeans, so I want to call this somehow.

it can


from sklearn.cluster.k_means_ import _k_init
from sklearn.utils.extmath import row_norms
import numpy as np

# x:data, k:Number of clusters
c = _k_init(x, k, row_norms(x, squared=True), np.random.RandomState())
