So far, the K-means algorithm is the most widely used method for discovering clusters in data, and it has been used extensively in the commercial field, such as customer analysis. However, the efficiency of the algorithm needs to be improved when faced with large amounts of data. The improved algorithm avoids unnecessary calculations by using the triangle inequality. We applies the improved algorithm...
Nowadays, clustering algorithms are widely used in the commercial field, such as customer analysis, and this application has achieved good effect. K-means algorithm is by far the most commonly used method for clustering. Although, the time consumption is fairly high when faced with lager-scale data. In this paper, we improved the K-means algorithm. Our improvement is based on the triangle inequality...
In this paper, an unsupervised fuzzy technique for segmentation of brain magnetic resonance (MR) images is presented, which combines fuzzy clustering algorithm with maximum a posteriori (MAP) criterion. As fuzzy C-means (FCM) tends to balance the number of points in each cluster, cluster centers of smaller clusters are drawn to larger adjacent clusters. In order to overcome this problem occurred in...
