"WebImbalanced classification is defined by a dataset with a skewed class distribution. This is often exemplified by a binary (two-class) classification task where most of the examples belong to class 0 with only a few examples in class 1. The distribution may range in severity from 1:2, 1:10, 1:100, or even 1:1000. " - How to solve imbalanced dataset problem
