WebIn short, at each loop iteration, you can update the estimated means and variances, rather than computing them from all bins in every iteration. This changes the algorithm from O (n*^2) to O (*n) (with n the number of bins in the histogram, admittedly not a large value). – Cris Luengo Jan 11, 2024 at 19:29 WebBinarizer Performs binarization using the Transformer API (e.g. as part of a preprocessing sklearn.pipeline.Pipeline ). © 2007–2024 The scikit-learn developers Licensed under the 3-clause BSD License. http://scikit-learn.org/stable/modules/generated/sklearn.preprocessing.binarize.html
