Confusion matrix metrics are essential tools for evaluating thee performance of conceped classifiers. They providee detailed insights into how well a model predicts different classes and help identify areas for improvit.

Understanding thee Confusion Matrix

Te confusion matrix is a table that summatizes the prediction results of a classification model. It displays the counts of true positives, true negatives, false positives, and false negatives. These values form tha basis for calculating various execurance metrics.

Key Metrics Derivek from tha Confusion Matrix

Several metrics can be calculated to evaluate a classifier 's effectiveness:

  • CLANE1; CLANE1; FLT: 0 CLANE3; CLANE3; Accuracy: CLANE1; CLANE1; FLT: 1 CLANE3; CLANE3; CLANE3; Te proportion of correct predictions s out of all predictions.
  • CLANE1; CLANE1; FLT: 0 CLANE3; CLANE3; Precision: CLANE1; CLANE1; FLT: 1 CLANE3; CLANE3; CLANE3; Te proportion of true positive predictions s among all positive predictions.
  • CLANE1; CLANE1; CLANE1; CLANE3; CLANE3; CLANE1; CLANE1; CLANE1; CLANE1; CLANE1; CLANE1; CLANE1; CLANE1; CLANE1; CLANE1; CLANE1; CLANE1; CLANE1; CLANE1; CLANE1; CLANE1; CLANE1; CLANE1; CLANE1; CLANE1; CLANE1; CLANE1; CLANE1; CLANE1; CLANE1; CLANE1; CLAU1; CTI1; CLAU1; CLAU1; CLAU1; CLAU1; CLAU1; CLAU1; CLAU1; CTI1; CLAUBLAUH3; CLAUCLAUBIVI3; CLANIVI3; CLAND; CLAND BLAND by TIVIDEF; CLAND; C@@
  • FLT: 0; FLT: 3; FST; F1 Score: FLAS 1; FLAS 1; FLT: 1; FLAS 3; FLAS 3; The harmonic mean of precision and recall, balancing both metrics.

Kalkulating metrics

Mettrics are calculated using thee following formulas:

Accuracy = (TP + TN) / (TP + TN + FP + FN)

Precision = TP / (TP + FP)

Recall = TP / (TP + FN)

F1 Score = 2 * (Precision * Recall) / (Precision + Recall)
