clustering method
91Clique (graph theory) — A graph with 23 1 vertex cliques (its vertices), 42 2 vertex cliques (its edges), 19 3 vertex cliques (the light blue triangles), and 2 4 vertex cliques (dark blue). Six of the edges and 11 of the triangles form maximal cliques. The two dark blue …
92Superlens — A superlens, super lens or perfect lens is a lens which uses metamaterials to go beyond the diffraction limit. The diffraction limit is an inherent limitation in conventional optical devices or lenses.[1] In 2000, a type of lens was proposed,… …
93CrimeStat — Primary File page of CrimeStat CrimeStat is a Windows based spatial statistic software program that conducts spatial and statistical analysis and is designed to interface with a Geographic Information System. The program is developed by Ned… …
94Drug design — Not to be confused with Designer drug. Drug design, also sometimes referred to as rational drug design or structure based drug design, is the inventive process of finding new medications based on the knowledge of the biological target.[1] The… …
95Eigenvalues and eigenvectors — For more specific information regarding the eigenvalues and eigenvectors of matrices, see Eigendecomposition of a matrix. In this shear mapping the red arrow changes direction but the blue arrow does not. Therefore the blue arrow is an… …
96Data Analysis Techniques for Fraud Detection — Fraud is a million dollar business and it is increasing every year. The PwC global economic crime survey of 2009 suggests that close to 30% of companies worldwide reported fallen victim to fraud in the past year[1] Fraud involves one or more… …

98Selection algorithm — In computer science, a selection algorithm is an algorithm for finding the kth smallest number in a list (such a number is called the kth order statistic). This includes the cases of finding the minimum, maximum, and median elements. There are… …
99Thresholding (image processing) — Thresholding is the simplest method of image segmentation. From a grayscale image, thresholding can be used to create binary images .During the thresholding process, individual pixels in an image are marked as “object” pixels if their value is… …
100Davies–Bouldin index — The Davies–Bouldin index (DBI) (introduced by David L. Davies and Donald W. Bouldin) in 1979 is a metric for evaluating clustering algorithms[1]. This is an internal evaluation scheme, where the validation of how well the clustering has been done …
