چکیده

Data mining technology has emerged as a means for identifying patterns and trends from large quantities of data. Clustering is a primary data description method in data mining which group’s most similar data. The data clustering is an important problem in a wide variety of fields. Including data mining, pattern recognition, and bioinformatics. It aims to organize a collection of data items into clusters, such that items within a cluster are more similar to each other than they are items in the other clusters. There are various algorithms used to solve this problem In this paper, we use FCM (Fuzzy C mean) clustering algorithm and MFPCM (Modified Fuzzy Possibililstic C mean) clustering algorithm. In this paper we compare the performance analysis of Fuzzy C mean (FCM) clustering algorithm and compare it with Modified Fuzzy possibililstic C mean algorithm. In this we compared FCM and MFPCM algorithm on different data sets. We measure complexity of FCM and MFPCM at different data sets. FCM clustering is a clustering technique which is separated from Modified Fuzzy Possibililstic C mean that employs Possibililstic partitioning. The FCM employs fuzzy portioning such that a point can belong to all groups with different membership grades between 0 and 1.

Image Segmentation: Type–2 Fuzzy Possibilistic C-Mean Clustering Approach

Image segmentation is an essential issue in image description and classification. Currently, in many real applications, segmentation is still mainly manual or strongly supervised by a human expert, which makes it irreproducible and deteriorating. Moreover, there are many uncertainties and vagueness in images, which crisp clustering and even Type-1 fuzzy clustering could not handle. Hence, Type-...

A study of various Fuzzy Clustering Algorithms

In data mining clustering techniques are used to group together the objects showing similar characteristics within the same cluster and the objects demonstrating different characteristics are grouped into clusters. Clustering approaches can be classified into two categories namelyHard clustering and Soft clustering. In hard clustering data is divided into clusters in such a way that each data i...

Hausdorff Distance Measure Based Interval Fuzzy Possibilistic C-Means Clustering Algorithm

Clustering algorithms have been widely used artificial intelligence, data mining and machine learning, etc. It is unsupervised classification and is divided into groups according to data sets. That is, the data sets of similarity partition belong to the same group; otherwise data sets divide other groups in the clustering algorithms. In general, to analysis interval data needs Type II fuzzy log...
