摘要:Data Release 12 is the final data release of the Sloan Digital Sky Survey (SDSS). We present a novel technique for automatically classifying massive stellar spectra selected from SDSS. The principal component analysis (PCA) is investigated to extract feature of spectra in conjunction with clustering method based on fast search and density peaks. After identifying groups of the cluster center, massive SDSS stellar spectra are classified to MK spectral classification. The result of the experiment indicates that the classification accuracy is up to 90% which proves the effectiveness of the method.
