What is the F1 Score?

Detailed Deep Dive

The F1-score is a performance evaluation metric that calculates the harmonic mean of precision and recall. It ranges from 0 to 1, where 1 indicates perfect precision and recall. The F1-score is particularly valuable for evaluating models trained on imbalanced datasets, as it balances the tradeoff between minimizing false positives (precision) and false negatives (recall).
