WebGiven a fixed number of bins, find and apply the maximum entropy: binning to an integer array, subject to the constraints that - each bin contains a consecutive series of integers, … WebData binning, also called data discrete binning or data bucketing, is a data pre-processing technique used to reduce the effects of minor observation errors. The original data values which fall into a given small interval, a bin, are replaced by a value representative of that interval, often a central value ( mean or median ).
