Solar activity classification based on Mg II spectra: towards classification on compressed data

Sergey Ivanov, Maksym Tsizh, Denis Ullmann +2

Although large volumes of solar data are available for study, the vast majority of these data remain unlabeled and are therefore not amenable to supervised machine learning methods…
