Example: Evaluating Classification Predictions


from sklearn.metrics import classification_report

y_true = [1, 0, 1, 1, 0, 0, 1]

y_pred = [1, 0, 1, 0, 0, 1, 1]

print(classification_report(y_true, y_pred))

📌 Why This Matters?

  • Helps identify model bias and errors.
  • Ensures predictions align with business objectives.
