recommendations! Published in 2018 at "Soft Computing"

DOI: 10.1007/s00500-016-2453-y

Abstract: To overcome the main problem of the cluster number in many clustering applications, a new clustering approach with improved morphology similarity distance and the novel cluster validity index is proposed in this paper. An optimized… read more here.

DOI: 10.1109/access.2025.3535417

Abstract: Cluster analysis is the process of associating data objects with classes of similar objects. One key aspect of the clustering problem is to determine the optimal number of groups on a data set to effectively… read more here.

recommendations! Published in 2020 at "IEEE Transactions on Fuzzy Systems"

DOI: 10.1109/tfuzz.2020.3016339

Abstract: Determining the correct number of clusters is essential for efficient clustering and cluster validity indices are widely used for the same. Generally, the effectiveness of a cluster validity index relies on two factors: (i) separation,… read more here.

DOI: 10.1109/tnnls.2022.3160381

Abstract: This article presents an adaptive resonance theory predictive mapping (ARTMAP) model, which uses incremental cluster validity indices (iCVIs) to perform unsupervised learning, namely, iCVI-ARTMAP. Incorporating iCVIs to the decision-making and many-to-one mapping capabilities of this… read more here.
