📊 Model Evaluation

I don't rely on a single metric.

Regression

MAE ───── RMSE ───── MSE ───── R²

Classification

Accuracy ─ Precision ─ Recall ─ F1
                  │
                  ▼
            ROC-AUC / PR-AUC

For problems such as fraud detection, precision, recall, ROC-AUC and especially PR-AUC can provide more useful information than accuracy alone.
