Feb 27, 2025 · A confusion matrix is a simple table that shows how well a classification model is performing by comparing its predictions to the actual results. It breaks down the predictions into four categories: correct predictions for both classes ( true positives and true negatives ) and incorrect predictions ( false positives and false negatives ).
