Class Imbalance: From Random Oversampling to ROSE

Let’s formally define the class imbalance problem then intuitively derive solutions for it!

Lately, I have been building a package to address class imbalance in Julia called Imbalance.jl. It took me a lot of effort in terms of reading papers and looking at implementations while building the package and I thought it may be helpful to share what I’ve learned about the class imbalance problem in general, along with some of the most popular algorithms used to tackle it. This …
