Structure Discovery and ClusteringClustering has been an area of intensive research for several decades because of its multifaceted applications in innumerable domains. Clustering can be either Boolean, where a single data point belongs to exactly one cluster, or fuzzy, where a single data point can...
To overcome the shortcomings of Fuzzy c﹎eans (FCM), a new fuzzy subspace clustering algorithm based on improved firefly algorithms is presented. In this approach, the global optimization capability of the firefly algorithm, strong local search features of FCM, and learning calculation for feature ...

The same framework allows the exact distribution of relative validity indices used to evaluate the quality of fuzzy clustering solutions. Complexity analyses for each distributed algorithm and index are reported in terms of space, time, and communication aspects. A general procedure to estimate the ...
Section 3 describes a fuzzy optimization process for mortality scoring, where a fuzzy classification model is described and a multi-objective constrained optimization model is proposed to learn accurate and comprehensible fuzzy classifiers. In Section 4 two Pareto-based elitist multi-objective algorithms ...

In molecular biology, for example, applying fuzzy-clustering to microarray data brings the advantage that the clustering result allows a gene to be assigned to more than one cluster [2], [6]. The problem, however, is how to assign the objects to one of the clusters. A common technique ...

When facing clustering problems for hesitant fuzzy information, we normally solve them on sample space by using a certain hesitant fuzzy clustering algorithm, which is usually time-consuming or generates inaccurate clustering results. To overcome the issue, we propose a novel hesitant fuzzy clustering ...
