Optimal binning method

WebThe optimal binning is the optimal discretization of a variable into bins given a dis-crete or continuous numeric target. We present a rigorous and extensible mathematical programming formulation to solve the optimal binning problem for a binary, contin-uous and multi-class target type, incorporating constraints not previously addressed.

WebApr 14, 2024 · Equal width (or distance) binning : The simplest binning approach is to partition the range of the variable into k equal-width intervals. The interval width is simply the range [A, B] of the variable divided by k, w = (B-A) / k. Thus, i th interval range will be [A + (i-1)w, A + iw] where i = 1, 2, 3…..k Skewed data cannot be handled well by this method.
