WebThe F0.5-measure is an example of the Fbeta-measure with a beta value of 0.5. It has the effect of raising the importance of precision and lowering the importance of recall. If maximizing precision minimizes false positives, and maximizing recall minimizes false negatives, then the F0.5-measure puts more attention on minimizing false positives ... http://www.pgia.pdn.ac.lk/pgia_mis/uploads/lecturenotes/51/3-FP&PD-D%20-Z-values-Shelf-life-NOTE.pdf
