WebThe F-beta score can be interpreted as a weighted harmonic mean of the precision and recall, where an F-beta score reaches its best value at 1 and worst score at 0. The F-beta score weights recall more than precision by a factor of beta. beta == 1.0 means recall and precision are equally important.

WebIf α = 1 2, the mean is balanced. A frequent equivalent formulation is F = ( β 2 + 1) ⋅ P ⋅ R R + β 2 ⋅ P. In this formulation, the mean is balanced if β = 1.
