TL;DR: In this paper , a hybrid convolutional neural network (CNN) was proposed for supercharged stellar parametrization by combining Gaia RVS spectra with the full set of Gaia products and high-resolution, high-quality spectroscopic reference data sets.
Machine learning techniques meet binaries

TL;DR: In this paper, a general dimensionality reduction technique is proposed to diagnose and classify a given data set, and in case of GALAH spectra, their method quite effectively reveals a population of SB2 and SB3 systems.

TL;DR: In this article , the authors used more than 872,000 mid-to-high resolution (R$20,000) spectra of stars from the GALAH survey to determine the spectrum of diffuse interstellar bands (DIBs).
