ISOMAP (Isometric Feature Mapping, and other metric feature mapping) algorithm can get more satisfactory results in high-dimensional nonlinear data processing, based on the MDS (Multi-Dimensional Scaling, multidimensional scaling), based on the basic idea is that when the data set distribution of low dimensional embedding manifold structure, you can get insurance the observation of spatial data sets mapped low dimensional space of representation .
