Doubt in weight estimation for handle the unbalanced dataset

[dhorka]

Hi,

I have a question related to the weight estimation for handle the imbalance training. In your paper the following formula is showed: w(y) = (N(y) -N(c_min) + lambda)/(N(c_max) - N(c_min)). However as far as I understand this formula is giving a high weight to classes that have more representation in the dataset and a low weight to the classes that have less representation. Is it a mistake? Can be that the numerator and denominator are switched?
