Validity index for crisp and fuzzy clusters
TLDR
A cluster validity index and its fuzzification is described, which can provide a measure of goodness of clustering on different partitions of a data set, and results demonstrating the superiority of the PBM-index in appropriately determining the number of clusters are provided.About:

A novel technique for fast determination of K in partitioning cluster analysis
Zeynel Cebeci,Cagatay Cebeci +1 more
TL;DR: The KPEAKS is proposed, a simple and fast technique based on the descriptive statistics of peak counts of the features for clustering multidimensional datasets that can be successfully used for determining k, the number of clusters to start all of the probabilistic and possibilistic partitioning algorithms.

Sampling and clustering algorithm for determining the number of clusters based on the rosette pattern
Ali Sadr,Amirkeyvan Momtaz +1 more
TL;DR: An algorithm for clustering the pixels in C -scan images without any initializing parameters is proposed and the results show that the algorithm improves the clustering capability and the efficiency of the algorithm in terms of cluster detection and run time improves considerably.

Fast Estimation for the Number of Clusters
TL;DR: In this article, a fast estimation solution based on the cluster centers selected in a static way is proposed to handle the accuracy problem of clustering analysis on overlapping data sets, where each data point is assigned with one score calculated according to a density-distance model.
