Parameters class_weight dict, ‘balanced’ or None If ‘balanced’, class weights will be given by n_samples / (n_classes * np.bincount(y)). Small addition to @MariosOreo’s answer: if your loss function uses reduction='mean', the loss will be normalized by the sum of the corresponding weights for each element.If you are using reduction='none', you would have to take care of the normalization yourself. They are a common choice for schools, colleges, and universities. To be more precise, the formula to calculate this is: wj=n_samples / (n_classes * n We offer Fractional Weights in all Classes viz, E1 Class, E2 Class, F1 Class, F2 Class and M1 Class.
