- Abstract:
-
As a new unsupervised learning method, manifold learning is capturing increasing interests of researchers in the field of machine learning and cogniti ve sciences. To understand manifold learning better, the topology concept of man ifold learning was presented firstly, and then its development history was trace d. Based on different representations of manifold, several major algo rithms were introduced, whose advantages and defects were pointed out resp ectively. After that , two kinds of typical applications of Isomap and LLE were indicated. The res ults show th at compared with traditional linear method, manifold learning can discover the in trinsic dimensions of nonlinear highdimensional data effectively, helping re searchers to reduce dimensionality and analyze data better. Finally the prospect of manifold learning was discussed, so as to extend the application area of man ifold learning.
