6.8.2. scikits.learn.cluster.MeanShift

class scikits.learn.cluster.MeanShift(bandwidth=None)

MeanShift clustering

Parameters :

bandwidth: float, optional :

Bandwith used in the RBF kernel If not set, the bandwidth is estimated. See clustering.estimate_bandwidth

Notes

Reference:

K. Funkunaga and L.D. Hosteler, “The Estimation of the Gradient of a Density Function, with Applications in Pattern Recognition”

The algorithmic complexity of the mean shift algorithm is O(T n^2) with n the number of samples and T the number of iterations. It is not adviced for a large number of samples.
