Galaxy Image Classification using Hierarchical Data Learning with Weighted Sampling and Label Smoothing
Xiaohua Ma, Xiangru Li, Ali Luo +2
With the development of a series of Galaxy sky surveys in recent years, the observations increased rapidly, which makes the research of machine learning methods for galaxy image re…
Estimating Atmospheric Parameters from LAMOST Low-Resolution Spectra with Low SNR
Xiangru Li, Si Zeng, Zhu Wang +3
Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) acquired tens of millions of low-resolution stellar spectra. The large amount of the spectra result in the urgenc…
A Model RRNet for Spectral Information Exploitation and LAMOST Medium-resolution Spectrum Parameter Estimation
Shengchun Xiong, Xiangru Li, Caixiu Liao
This work proposes a Residual Recurrent Neural Network (RRNet) for synthetically extracting spectral information, and estimating stellar atmospheric parameters together with 15 che…
Estimation of stellar atmospheric parameters from LAMOST DR8 low-resolution spectra with 20SNR30
Xiangru Li, Zhu Wang, Si Zeng +4
The accuracy of the estimated stellar atmospheric parameter decreases evidently with the decreasing of spectral signal-to-noise ratio (SNR) and there are a huge amount of this kind…
