SpecTE: Parameter Estimation for LAMOST Low-resolution Stellar Spectra Based on Denoising Pretraining
This paper proposes a spectral transformer encoder (SpecTE) model based on a denoising pretraining technique, and applies it to estimating radial velocity (RV) and three stellar atmospheric physical parameters together with 15 chemical element abundances from low-resolution spectra from the Large Sk...
