A correct choice of k depends on both size and density of data. The resulting graph contains all the edges with weights greater than zero. Second, fuzzy clustering is applied to form dense clusters found in the SNN …
WebbThe shared nearest neighbors ( N) represent the average number of features per cluster. To compute the same, the total number of features is divided by the number of features in the resultant feature set (S), if S is the ideal feature subset. Equation (5) defines the mathematical formulation of shared nearest neighbors ( N ). (5) 2.5.
