Abstract
The paper deals with classification of Be star spectra using discrete wavelet transform (DWT), stationary wavelet transform (SWT) and support vector machines (SVM).
Keywords

Annotation
Our goal is to automatically identify Be and B[e] stars spectra in large archives and classify their types. Due to the length of spectra, the dimension reduction is required. As the Be stars show a number of different shapes of emission lines, it is not easy to construct simple criteria to identify the emission lines. We propose to perform the wavelet transform and apply statistical metrics on the wavelet coefficients. The results show that using proposed method we can reduce the number of attributes and the processing time to a small fraction, and moreover increase the accuracy.
