F1-Score — AWS AI Practitioner (AIF-C01) Practice Questions
The F1-score is the harmonic mean of precision and recall, providing a single balanced measure for classification performance especially when classes are imbalanced. AIF-C01 candidates should understand why accuracy alone can be misleading on skewed datasets and when F1 is preferable over either precision or recall independently. The exam may also reference macro-averaged and weighted F1 variants when evaluating multiclass models.
