Researchers have introduced novel absolute cluster indices designed to determine the compactness and separability of clusters within datasets. Unlike existing relative indices that compare algorithms or parameters, these new indices offer a direct measure of cluster quality. The proposed method defines a compactness function for individual clusters and a set of neighboring points for cluster pairs, which is then used to assess the overall distribution margin. These indices are applied to identify the optimal number of clusters and have demonstrated performance comparable to widely-used cluster validity indices on various synthetic and real-world datasets.
