Estimating stellar atmospheric parameters based on LASSO and support-vector regression
Yu Lu, Xiangru Li
A scheme for estimating atmospheric parameters T, log, and [Fe/H] is proposed on the basis of Least Absolute Shrinkage and Selection Operator (LASSO) algorithm and Haar…
An autoencoder of stellar spectra and its application in automatically estimating atmospheric parameters
Tan Yang, Xiangru Li
This article investigates the problem of estimating stellar atmospheric parameters from spectra. Feature extraction is a key procedure in estimating stellar parameters automaticall…
SDSS/SEGUE Spectral Feature Analysis For Stellar Atmospheric Parameter Estimation
Xiangru Li, Q. M. Jonathan Wu, Ali Luo +5
Large-scale and deep sky survey missions are rapidly collecting a large amount of stellar spectra, which necessitate the estimation of atmospheric parameters directly from spectra…
Linearly Supporting Feature Extraction For Automated Estimation Of Stellar Atmospheric Parameters
Xiangru Li, Yu Lu, Georges Comte +3
We describe a scheme to extract linearly supporting (LSU) features from stellar spectra to automatically estimate the atmospheric parameters , log, and [Fe/H]. "Linear…
