Inferring Cosmological Parameters on SDSS via Domain-Generalized Neural Networks and Lightcone Simulations

Jun-Young Lee, Ji-hoon Kim, Minyong Jung +6

We present a proof-of-concept simulation-based inference on ${\Omega }_{\mathrm{m}}$ and ${\sigma }_8$ from the SDSS BOSS LOWZ NGC catalog using neural networks and domain generalization techniques w…
