چکیده

-Clustering algorithms are an integral part of both computational intelligence and pattern recognition. It is unsupervised methods for classifying data into subgroups with similarity based inter cluster and intra cluster. In fuzzy clustering algorithms, mainly used algorithm is Fuzzy c-means (FCM) algorithm. This FCM algorithm is efficient only for spherical data when the input of the data structure is not spherical or complex this method is unsuccessful. For this, modification of the FCM is done by the labeling of a pixel to be partial by the labels in its immediate neighborhood and this modification is called BCFCM (Bias-Corrected FCM). Since it is computationally time taking and lacks enough robustness to noise for that kernel versions of FCM with spatial constraints, such as KFCM, were proposed to solve the drawbacks of BCFCM. In this paper, a novel kernel-based fuzzy C-means clustering algorithm (KFCM) is proposed for clustering. It is recognized by replacing the kernel-induced distance metric over the original Euclidean distance, and the corresponding algorithms are called kernel fuzzy c-means (KFCM) algorithm. The experimental results shows that proposed clustering technique provides better accuracy with less error rate than the BCFCM algorithm. Keywords--Clustering, Fuzzy clustering, Bias corrected Fuzzy C Means, Kernel based Fuzzy C Means

Spatial Bias Correction Based on Gaussian Kernel Fuzzy C Means in Clustering

Clustering is the process of grouping data objects into set of disjointed classes called clusters so that objects within a class are highly similar to one another and dissimilar to the objects in other classes. K-means (KM) and Fuzzy c-means (FCM) algorithms are popular and powerful methods for cluster analysis. However, the KM and FCM algorithms have considerable trouble in a noisy environment...

Entropy-based Consensus for Distributed Data Clustering

The increasingly larger scale of available data and the more restrictive concerns on their privacy are some of the challenging aspects of data mining today. In this paper, Entropy-based Consensus on Cluster Centers (EC3) is introduced for clustering in distributed systems with a consideration for confidentiality of data; i.e. it is the negotiations among local cluster centers that are used in t...
