Evaluating a classification model involves measuring how well it predicts categorical outcomes. Key methods and metrics include:

1. Confusion Matrix – Shows the counts of true positives (TP), true negatives (TN), false positives (FP), and false negatives (FN), providing a detailed view of model performance.

2. Accuracy – Proportion of correct predictions:

   $$\text{Accuracy} = \frac{TP + TN}{TP + TN + FP + FN}$$

   Useful for balanced datasets but can be misleading if classes are imbalanced.

3. Precision – Measures correctness of positive predictions:

   $$\text{Precision} = \frac{TP}{TP + FP}$$

4. Recall (Sensitivity) – Measures how well the model identifies actual positives:

   $$\text{Recall} = \frac{TP}{TP + FN}$$

5. F1-Score – Harmonic mean of precision and recall, balances both metrics:

   $$F1 = 2 \times \frac{\text{Precision} \times \text{Recall}}{\text{Precision} + \text{Recall}}$$

6. ROC Curve and AUC – ROC curve plots true positive rate vs false positive rate at different thresholds; AUC measures overall separability of classes.

7. Cross-Validation – Splitting data into multiple folds to test model stability and avoid overfitting.

Summary: Use a combination of metrics, depending on the problem and class balance, to get a comprehensive view of model performance.
