'''Local tangent space alignment (LTSA)''' is a method for manifold learning, which can efficiently learn a nonlinear embedding into low-dimensional coordinates offrom [[high-dimensional]] data, and can also reconstruct high -dimensional coordinates from embedding coordinates. But it ignores the label information conveyed by data samples, and thus can not be used for classification directly.
