A Gaussian Process framework for constraining the nuclear equation of state from microscopic calculations with correlated uncertainties
Y. G. Lee, J. Kim, T. Zhao +1
We present constraints on the nuclear equation of state (EOS) from microscopic asymmetric matter calculations at zero temperature based on chiral nucleon-nucleon and three-nucleon…
A Semi-Supervised Variational Autoencoder for Generating Neutron Star Equations of State
Tianqi Zhao, Fanglida Yan, Alex Ross +1
We develop a semi-supervised variational autoencoder (SSVAE) framework to reconstruct and generate neutron star (NS) equations of state (EOS). The SSVAE consists of an encoder netw…
A Very Big Video Reasoning Suite
Maijunxian Wang, Ruisi Wang, Juyi Lin +53
Rapid progress in video models has largely focused on visual quality, leaving their reasoning capabilities underexplored. Video reasoning grounds intelligence in spatiotemporally c…
Data-Driven Generation of Neutron Star Equations of State Using Variational Autoencoders
Alex Ross, Tianqi Zhao, Sanjay Reddy
We develop a machine learning model based on a structured variational autoencoder (VAE) framework to reconstruct and generate neutron star (NS) equations of state (EOS). The VAE co…
A New Bayesian Framework with Natural Priors to Constrain the Neutron Star Equation of State
Boyang Sun, Tianqi Zhao, James M. Lattimer
We propose a new Bayesian framework to infer the neutron star equation of state (EOS) from mass and radius observations and neutron matter theory by defining priors that directly p…
Observable Signatures of a Quarkyonic Phase in Neutron Stars
Probit J Kalita, Tuhin Malik, Tianqi Zhao +2
Quarkyonic matter in \(β\)-equilibrium is a potential description of cold dense matter in neutron stars (NSs), that introduces non-interacting quarks alongside nucleons and lepton…
