When does a dataset become ‘imbalanced’? The notion of an imbalanced dataset is a somewhat vague one. Generally, a dataset for binary classification with a 49–51 split between the two variables would not be considered imbalanced. However, if we have a dataset with a 90–10 split, it seems obvious to us that this is an imbalanced dataset.
