In this paper manifold embedding and reconstruction procedures are considered in the scope of unsupervised dimension reduction problem. Standard approaches (Isomap, LLE, LTSA, etc.) are compared to newly proposed Grassman-Stiefel Eigenmaps (GSE) algorithm. It turned out that GSE provides best manifold reconstruction abilities on test problems.
