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-...
Clustering of objects is an important area of research and application in variety of fields. In this paper we present a good technique for data clustering and application of this Technique for data clustering in a closed area. We compare this method with K-nearest neighbor and K-means.
Identifying clusters is an important aspect of data analysis. This paper proposes a noveldata clustering algorithm to increase the clustering accuracy. A novel game theoretic self-organizingmap (NGTSOM ) and neural gas (NG) are used in combination with Competitive Hebbian Learning(CHL) to improve the quality of the map and provide a better vector quantization (VQ) for clusteringdata. Different ...
Clustering algorithms are highly dependent on different factors such as the number of clusters, the specific clustering algorithm, and the used distance measure. Inspired from ensemble classification, one approach to reduce the effect of these factors on the final clustering is ensemble clustering. Since weighting the base classifiers has been a successful idea in ensemble classification, in th...
The rapid progress in the field of information technology, especially internet, has given birth to a lot information. ease publishing an article on website causes explosion news pages which will certainly confuse readers. diversity and increasing number articles make it increasingly difficult for internet users find large piles data online newspaper sites Aceh. grouping text documents is needed...
Supermarkets are Indonesian terms that refer to large stores or supermarkets offer a variety of daily needs such as food, drinks, cleaning products, household appliances, clothing, and so on. In contrast stalls small shops, have larger size provide products. Because this, many people prefer shop for their at the supermarket rather than nearest because existence makes it easier consumers buy var...
one of the most important aspects of software project management is the estimation of cost and time required for running information system. therefore, software managers try to carry estimation based on behavior, properties, and project restrictions. software cost estimation refers to the process of development requirement prediction of software system. various kinds of effort estimation patter...
Electric distribution companies regulation has important effect on power system. Distribution services costing are done by two method, price base and performance base. Distribution company cost include operational and investment. Services quality, productivity improvement and etc are applied by benchmarking. With regard to different condition of companies, it is important that regulator benchma...
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...
