WebA demonstration of feature discretization on synthetic classification datasets. Feature discretization decomposes each feature into a set of bins, here equally distributed in width. The discrete values are then one-hot … Webwoebin generates optimal binning for numerical, factor and categorical variables using methods including tree-like segmentation or chi-square merge. woebin can also customizing breakpoints if the breaks_list was provided. The default woe is defined as ln(Pos_i/Neg_i). If you prefer ln(Neg_i/Pos_i), please set the argument positive as negative …

R: Discretization using ChiMerge algorithm

WebOutput: 15. However: print (min (x for x in range (1,300) if x % 2 != 0 if x % 2 != 1)) Output: ValueError: min () arg is an empty sequence. There are no integers that are both odd and even, so there are no values for min to see, so it throws an exception. I deduce that in your code, there are no values that pass both conditions.
