Imbalanced dataset in machine learning
WitrynaHow to deal with imbalanced datasets is a traditional but still everlasting problem in data mining. Most standard machine learning algorithms assume a balanced class distribution or an equal misclassification cost. As a result, their performance for predicting uneven data might get doomed by the various difficulties imbalanced classes may … Witryna11 lis 2024 · Balanced and Imbalanced Datasets in Machine Learning [Introduction] When it comes to determining model performance, ML engineers need to know if their classification models are predicting accurately. However, because of the accuracy paradox, they should never rely on accuracy alone to evaluate a model’s performance.
