ScaEcn: A Spectral Clustering Algorithm for Automatically Estimating the Clustering Number

This paper proposes an Algorithm for Automatically Estimating the Clustering Number based on Spectral Clustering Algorithm—ScaEcn, which estimates the clustering number via computing the amount of eigenvalue equals to 1 in Laplace matrix. The fabricating data-set and UCI data-set have been used in the experiment; the result indicates that the ScaEcn has satisfactory effect in both fabricating data set and UCI data set.
