[ascl:2306.032] CosmoGraphNet: Cosmological parameters and galaxy power spectrum from galaxy catalogs

CosmoGraphNet infers cosmological parameters or the galaxy power spectrum. It creates a graph from a galaxy catalog with information the 3D position and intrinsic galactic properties. A Graph Neural Network is then applied to predict the cosmological parameters or the galaxy power spectrum.
