Binary classification accuracy
WebJust multiplying and then dividing accuracy and recall results in the F1 score. The F1 score, for instance, is 2* (83.3*80)/ (83.3+80) = 81.6% if the accuracy of a classification model is 5/6, or 83.3%, and the recall is 4/5, or 80%. A classification model's F1 score is a crucial performance indicator since it shows how effectively the model ... WebSep 7, 2024 · Accuracy is a very simple evaluation measure for binary classification, it's suitable only if the data is perfectly balanced. It's likely that observing precision and recall would provide some insight about the differences between classifiers. Of course, results depend a lot on the data. For example it could be that around 58% of the instances ...
