Scipy k-means
WebThe k-means algorithm takes as input the number of clusters to generate, k, and a set of observation vectors to cluster. It returns a set of centroids, one for each of the k clusters. … WebEverything in the namespaces of scipy submodules is public. In general, it is recommended to import functions from submodule namespaces. For example, the function curve_fit (defined in scipy/optimize/_minpack_py.py) should be imported like this: from scipy import optimize result = optimize.curve_fit(...)
