Rotation-invariant convolutional neural networks for galaxy morphology prediction

Autor: Joni Dambre, Kyle W. Willett, Sander Dieleman

Publikováno v: Monthly Notices of the Royal Astronomical Society. 450:1441-1459

Measuring the morphological parameters of galaxies is a key requirement for studying their formation and evolution. Surveys such as the Sloan Digital Sky Survey (SDSS) have resulted in the availability of very large collections of images, which have
