A new heuristic algorithm of fuzzy clustering
This paper deals with a new method of fuzzy clustering. The basic concepts of the method are introduced as resulting from the consideration of the fundamental fuzzy clustering problem. The paper provides the description of the general plan of the algorithm and an illustrative example. An analysis of the experimental results of the method’s application to the Anderson’s Iris data is carried out....
متن کاملHC_AB: A new heuristic clustering algorithm based on Approximate Backbone
a r t i c l e i n f o a b s t r a c t Clustering is an important research area with numerous applications in pattern recognition, machine learning, and data mining. Since the clustering problem on numeric data sets can be formulated as a typical combinatorial optimization problem, many researches have addressed the design of heuristic algorithms for finding sub-optimal solutions in a reasonable...
متن کاملA Fuzzy C-means Algorithm for Clustering Fuzzy Data and Its Application in Clustering Incomplete Data
The fuzzy c-means clustering algorithm is a useful tool for clustering; but it is convenient only for crisp complete data. In this article, an enhancement of the algorithm is proposed which is suitable for clustering trapezoidal fuzzy data. A linear ranking function is used to define a distance for trapezoidal fuzzy data. Then, as an application, a method based on the proposed algorithm is pres...

متن کاملNew Clustering Algorithm for Multidimensional Data
Calculating similarity for multidimensional data is one of the key problems that must be addressed in order to promote the development of data clustering algorithms. In this study, we developed and tested a new similarity calculation index to improve the accuracy of multidimensional data clustering. First, the information divergence (ID) and generalized gradient angle (GGZ) were explored in det...
