Self-Tuning Spectral Clustering - NeurIPS

WebIn this paper we investigate the limit behavior of a class of spectral clustering algorithms. Spectral clustering is a popular technique going back to Donath and Hoffman (1973) and Fiedler (1973). In its simplest form it uses the second eigenvector of the graph Laplacian matrix constructed from the afﬁnity graph between the sample points Webspectral clustering methods have drawn increasing attention from researchers around the world and have been utilized in many applications. Usually, spectral clustering consists of two separate steps [14], i.e., contructing an afﬁnity matrix and performing clustering on the generated afﬁnity matrix.
