Hi all, I am facing the imbalanced classification problems. That means I have a dataset, in which the ratio of majority data to minority data is 100:1 (or more).
In addition, the independent variables are many and this is a binary classification questions. The model I built give poor predictive power for minor data, but for the majority data the predictivity seems to overfitting. Could you give me a suggestions to solve the imbalanced classification problems? Thanks in advance!
