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. It’s bounded between 0 and 1, with higher values being better. metrics.fowlkes_mallows_score(predicted_labels, actual)
