Research ArticleOpen accessAll words, across the recordAn Efficient Approach for Computing Silhouette CoefficientsMoh'd B. Al- Zoubi, Mohammad al RawiOne popular approach for finding the best number of clusters (K) in a data set is through computing the silhouette coefficients. The silhouette coefficients for different values of K, are first found and then the maximum value of these coefficients is chosen. However, computing the silhouette coefficient for different Ks is a very time consuming process. This is due to … …Journal of Computer Science, Vol. 4, Issue 3 · 31 Mar 2008 · 8,067 accessesView PDFCite
