Lux: A Generative, Multioutput, Latent-variable Model for Astronomical Data with Noisy Labels
The Astronomical JournalThe large volume of spectroscopic data available now and from near-future surveys will enable high-dimensional measurements of stellar parameters and properties. Current methods for determining stellar labels from spectra use physics-driven models, which

A statistical analysis of two-dimensional patterns and its application to astrometry
, 2018 Here we develop a general statistical procedure for the analysis of finite two-dimensional (2D) patterns inspired by the analysis of heavy-ion data. The method is used in the study of publicly available data obtained by the Gaia-ESA mission.
