The Fowlkes–Mallows index is an external evaluation method that is used to determine the similarity between two clusterings (clusters obtained after a clustering algorithm), and also a metric to measure confusion matrices. This measure of similarity could be either between two hierarchical … See more The Fowlkes–Mallows index, when results of two clustering algorithms are used to evaluate the results, is defined as where $${\displaystyle TP}$$ is the number of See more Since the index is directly proportional to the number of true positives, a higher index means greater similarity between the two clusterings used to determine the index.
