WebOct 29, 2024 · 2 Answers. Class weights typically do not need to normalise to 1 (it's only the ratio of the class weights that is important, so demanding that they sum to 1 would not actually be a restriction though). So setting the class weights to 0.4 and 0.9 is equivalent to assuming a split of class labels in the data of 0.4 / (0.4+0.9) to 0.9 / (0.4+0.9 ...
