The F-measure or balanced F-score, which combines precision and recall, is the harmonic mean of precision and recall. The performance of aggregated keywords is measured in terms of the overall performance of the application. However, this entails the influence of parameters besides the keywords ...

One common example of the use of the harmonic mean in machine learning is in the calculation of the F-Measure (also the F1-Measure or the Fbeta-Measure); that is a model evaluation metric that is calculated as the harmonic mean of the precision and recall metrics. The harmonic mean can...

Supraharmonic emissions are emitted regularly at switching frequency and its integer multiples, and a priori knowledge about the distribution of supraharmonic signals is a prerequisite for applying this index. F-measure is the weighted harmonic average of recall and precision. The precision is relative...
