Active deep learning method for the discovery of objects of interest in large spectroscopic surveys

Petr Škoda,
Ondřej Podsztavek,
Pavel Tvrdík

Abstract: Context. Current archives of the LAMOST telescope contain millions of pipeline-processed spectra that have probably never been seen by human eyes. Most of the rare objects with interesting physical properties, however, can only be identified by visual analysis of their characteristic spectral features. A proper combination of interactive visualisation with modern machine learning techniques opens new ways to discover such objects. Aims. We apply active learning classification methods supported by deep convolut… Show more
