Volume and Surface Area-Based Cluster Validity Index
IEEE Access, 2020 Cluster validity index plays an important role in assessing the quality of clustering results. However, most of the existing validity indices take a trial-and-error strategy, and their correctness depend on not only the measurements of intra- and inter ...

A New Cluster Validity Index Based on the Adjustment of Within-Cluster Distance
IEEE Access, 2020 The evaluation on clustering results is an important component of clustering analysis, which can be conducted by the cluster validity index. However, the performances of most existing indices depend on not only the specific clustering algorithms but also

Statistics Notes: Validating scales and indexes [PDF]
BMJ, 2002 An index of quality is a measurement like any other, whether it is assessing a website, as in today's BMJ ,1 a clinical trial used in a meta-analysis,2 or the quality of a life experienced by a patient.3 As with all measurements, we have to decide whether it measures what we want it to measure, and how well.

A Generalized Clustering Method Based on Validity Indices and Membership Functions
IEEE Access, 2018 Clustering is an important task in data analysis to find a partition on an unlabeled dataset based on similarity relationships among its elements. Typically, such similarity is determined by a proximity measure or distance. Then, the optimal partition is

Electrical fuzzy C-means: A new heuristic fuzzy clustering algorithm
Cogent Engineering, 2016 Many heuristic and meta-heuristic algorithms have been successfully applied in the literature to solve the clustering problems. The algorithms have been created for partitioning and classifying a set of data because of two main purposes: at first, for ...
