What is F score in machine learning?
- The F-score is also used in machine learning. Note, however, that the F-measures do not take the true negatives into account, and that measures such as the Matthews correlation coefficient , Informedness or Cohen's kappa may be preferable to assess the performance of a binary classifier.
