A Note on Comparison of F-measures

This work has been submitted to the IEEE for possible publication. Abstract--We comment on a recent TKDE paper [1] "Linear Approximation of F-measure for the Performance Evaluation of Classification Algorithms on Imbalanced Data Sets", and make two improvements related to comparison of F-measures for two prediction rules. We extend the "JVESR formula" We found in a recent issue of TKDE Wong's paper [1] performance of the proposed method and Wong's method on statistical comparison of F-measures for two algorithms, with the designed comparative experiments. Finally, we which is obviously an important problem. However, we conclude and discuss possible future works in Section 4. found that there are two things in [1] that need improvement.
