- W2380605989 abstract "In this paper, through researching automatic identification of the spectrum, we researched the rules of the spectrum of stars, and advanced an efficient and quick method based on 2-d pca and hierarchical clustering method is proposed. Using the PCA methol, we build the spectrum main heft, and distilled the main character of spectrum. The coordinates are achieved by projecting the high dimensional data to the 2-Dspace after the principle component space is built, then the corrdinates can be clustered by hierarchical clustering method, thus the high dimensional data can be dealt with quickly and automatically." @default.
