%X An efficient and quick method based on 2-D pca and hierarchical clustering method is proposed. The coordinates are achieved by projecting the high dimensional celestial objects spectra data to the 2-D space after the principle component space is built, every principle component is the linear combination of the original variables and is irrelevant to each other. The coordinates can be clustered by hierarchical clustering method. An automatic celestial objects spectra classification software is designed based...
