RMSE против MAE | AWS Certified AI Practitioner (AIF-C01)

AWS Certified AI Practitioner (AIF-C01) candidates: learn to choose between RMSE and MAE for regression evaluation and spot the exam-style cues that matter. AWS Certified AI Practitioner (AIF-C01) practical tip: understand why RMSE is more sensitive to large errors and when that sensitivity is a feature or a bug. Distinguish regression from classification and why metric choice differs. Define Mean Absolute Error (MAE) with intuition and interpretation. Define Root Mean Squared Error (RMSE) and explain sensitivity to large errors. Compare MAE vs RMSE with practical decision rules and examples. Apply a simple exam-style decision rule to pick the right metric for a scenario. Exam decision rule: If large errors need heavier punishment, prefer RMSE; if you want equal weight per unit error, prefer MAE.
