Abstract
Machine learning is used to obtain ratios of 100–500-MeV positron-to-electron and electron-to-proton fluxes with rigidities of 1–1.7-GV from the PAMELA experimental data for 2006–2016 in order to study the solar modulation of cosmic-ray fluxes with energies below 1 GeV. Observed features of the data and a comparison to AMS-02 experimental results allow study of the charge–sign dependence of modulation around the sunspot minimum in 2009 and the maximum in 2015.
