Top 8 Ways To Manage Imbalanced Classes In Your Dataset

Ambika Choudhury classification problems

Imbalanced classes in a dataset are often usual among classification problems in machine learning. Balancing an imbalanced class is crucial as the classification model, which is trained using the imbalanced class dataset will tend to exhibit the prediction accuracy according to the highest class of the dataset. Researchers have proposed several approaches to deal with…
