WebThe Fowlkes-Mallows function measures the similarity of two clustering of a set of points. It may be defined as the geometric mean of the pairwise precision and recall. Mathematically, F M S = T P ( T P + F P) ( T P + F N) Here, TP = True Positive − number of pair of points belonging to the same clusters in true as well as predicted labels both.
