Fowlkes-mallows index
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.

WebMay 15, 2024 · Fowlkes Mallows Score. The Fowlkes Mallow Score is similar, in as much that it tells you the degree to which cluster assignments are ‘correct’. In particular, it calculates the geometric mean between precision and recall.
