Neural-network-derived Stellar Parameters and Distances for Cool Giants

In this work, we employ a multilayer perceptron to derive atmospheric parameters (effective temperature Teff, surface gravity logg , and metallicity [M/H]) for a large sample of cool giants from LAMOST DR9 low-resolution spectra. For spectra with a median signal-to-noise ratio ∼ 105, the achieved internal precisions ar...
