Web11 Dec 2024 · If the distribution of the labels is not moderately uniform, then the dataset is called imbalanced. Case 1: In a two-class classification problem, let’s say you have 100k data points. It is imbalanced if only 10k data points are from class 1 and rest of them are from class 2. The distribution ratio here is 1:9. WebMachine learning. Imbalanced dataset is relevant primarily in the context of supervised machine learning involving two or more classes. Imbalance means that the number of data points available for different the classes is different: If there are two classes, then balanced data would mean 50% points for each of the class.
