Geometric Structure of High-Dimensional Data system on a data set defines a data graph, which can be considered as a discrete form of a manifold. In Section 2, we introduce the basic concepts of graphs. In Section 3, the spectral graph analysis is introduced as a tool for analyzing the data geometry. Particularly, the Laplacian on a graph is

In Section 11.1, we describe the method, paying more attention to the global alignment technique. In Section 11.2, the LTSA algor
