چکیده

Like k-means and Gaussian mixture model (GMM), fuzzy c-means (FCM) with soft partition has also become a popular clustering algorithm still is extensively studied. However, these algorithms their variants suffer from some difficulties such as determination of the optimal number clusters which key factor for quality. A common approach overcoming this difficulty to use trial-and-validation strategy, i.e., traversing every integer large like ?n 2 until finding corresponding peak value cluster validity index. But it scarcely possible naturally construct an adaptively agglomerative hierarchical structure using strategy. Even if possible, existing different indices lead clusters. To effectively mitigate problems while motivated by convex clustering, in article we present centroid auto-fused method (CAF-HFCM) whose optimization procedure can automatically agglomerate form hierarchy, more importantly, yielding without resorting any Although recently proposed robust-learning (RL-FCM) obtain best help index, so-involved three hyperparameters need adjust expensively, conversely, our CAF-HFCM involves just one hyperparameter makes adjustment relatively easier operational. Further, additional benefit objective, reduces sensitivity initialization performance. Moreover, able be straightforwardly extended various FCM. Finally, extensive experiments on both synthetic real data sets demonstrate effectiveness efficiency CAF-HFCM.

OPTIMIZATION OF FUZZY CLUSTERING CRITERIA BY A HYBRID PSO AND FUZZY C-MEANS CLUSTERING ALGORITHM

This paper presents an efficient hybrid method, namely fuzzy particleswarm optimization (FPSO) and fuzzy c-means (FCM) algorithms, to solve the fuzzyclustering problem, especially for large sizes. When the problem becomes large, theFCM algorithm may result in uneven distribution of data, making it difficult to findan optimal solution in reasonable amount of time. The PSO algorithm does find ago...

Bilateral Weighted Fuzzy C-Means Clustering

Nowadays, the Fuzzy C-Means method has become one of the most popular clustering methods based on minimization of a criterion function. However, the performance of this clustering algorithm may be significantly degraded in the presence of noise. This paper presents a robust clustering algorithm called Bilateral Weighted Fuzzy CMeans (BWFCM). We used a new objective function that uses some k...

A 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...
