Evaluation metrics for classification ML model
Accuracy: measures the overall correctness of the model
Precision: measures the proportion of true positive predictions among all positive predictions
Recall: measures the proportion of true positive predictions among all actual positives
F1 Score: harmonic mean of precision and recall
Confusion Matrix: provides a summary of correct and incorrect predictions
Precision and recall are used in evaluating the performance of classification models.
Precision is used when the goal is to minimize false positives.
Recall is used when the goal is to minimize false negatives.
Precision is calculated as TP / (TP + FP) where TP is true positives and FP is false positives.
