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:

Modelling and clustering of gene expressions using rbfs and a shape similarity metric
Carla S. Möller-Levet,Hujun Yin +1 more
TL;DR: A novel approach for gene expression time-series modelling and clustering using neural networks and a shape similarity metric is introduced and it is identified that the use of the correlation coefficient of the derivative of the modelled profiles allows the comparison of profiles based on their shapes and the distributions of time points.

A Fast Algorithm to Initialize Cluster Centroids in Fuzzy Clustering Applications
Zeynel Cebeci,Cagatay Cebeci +1 more
TL;DR: The InoFrep is a novel data-dependent initialization algorithm for improving computational efficiency and robustness in prototype-based hard and fuzzy clustering and can be applied to multidimensional large datasets because of its shorter initialization time and independence from dimensionality due to working with only one feature with the highest number of peaks.

Dissertation
Evaluating Clusterings by Estimating Clarity
TL;DR: It is shown that informativeness can be used to select clusterings which lead to superior spam filters when few true labels are available and its use in a realistic application: email spam filtering.
