   def     _lloyd_iteration (    sample  :  np.ndarray    ,    decay  :  float    ,    qhull_options  :  str      )   →  np.ndarray

Lloyd-Max algorithm iteration.

sample : array_like (n, d): The sample to iterate on.
decay : float: Relaxation decay. A positive value would move the samples toward their centroid, and negative value would move them away. 1 would move the samples to their centroid.
qhull_options : str: Additional options to pass to Qhull. See Qhull manual for details. (Default: "Qbb Qc Qz Qj Qx" for ndim > 4 and "Qbb Qc Qz Qj" otherwise.)

sample : array_like (n, d): The sample after an iteration of Lloyd's algorithm.
