confusion matrix

Syllable breakdown

Dictionary meaning

a table used to evaluate the performance of a classification model by comparing predicted class labels against true labels across all samples; the cells contain counts of true positives, true negatives, false positives, and false negatives; from these, metrics including accuracy, precision, recall, F1-score, and the Matthew's correlation coefficient can be computed; particularly important for imbalanced datasets where overall accuracy is a misleading indicator of model quality
