3. Model Comparison

🏆 Best Model: Support Vector Machine — Accuracy: 0.9825

All Models

Understanding the Metrics:

Accuracy

% of all predictions correct. Best for balanced datasets.

Precision

Of positive predictions, how many are actually positive. Matters when false positives are costly.

Recall

Of actual positives, how many were caught. Matters when missing positives is costly.

F1

Balance of precision & recall. Best for imbalanced datasets.
