In other words: isNaN() converts the value to a number before testing it. WebMar 8, 2024 · F1-score: F1 score also known as balanced F-score or F-measure. It's the harmonic mean of the precision and recall. F1 Score is helpful when you want to seek a balance between Precision and Recall. The closer to 1.00, the better. An F1 score reaches its best value at 1.00 and worst score at 0.00. It tells you how precise your classifier is. gobet philippe

WebJul 3, 2024 · This is called the macro-averaged F1-score, or the macro-F1 for short, and is computed as a simple arithmetic mean of our per-class F1-scores: Macro-F1 = (42.1% + 30.8% + 66.7%) / 3 = 46.5% In a similar way, we can also compute the macro-averaged precision and the macro-averaged recall: WebThe relative contribution of precision and recall to the F1 score are equal. The formula for the F1 score is: F1 = 2 * (precision * recall) / (precision + recall) In the multi-class and multi-label case, this is the average of the F1 score of each class with weighting depending on the average parameter.
