Generalization from Low- to Moderate-Resolution Spectra with Neural Networks for Stellar Parameter Estimation: A Case Study with DESI

Xiaosheng Zhao, Yuan-Sen Ting, Rosemary F. G. Wyse +5

Cross-survey generalization is a critical challenge in stellar spectral analysis, particularly in cases such as transferring from low- to moderate-resolution surveys. We investigat…

Machine Learning Techniques to Distinguish Giant Stars from Dwarf Stars Using Only Photometry -- Pushing Redwards

Keyi Ding, Carrie Filion, Rosemary F. G. Wyse +6

We present our photometric method, which combines Subaru/HSC NB515, g, and i band filters to distinguish giant stars in Local Group galaxies from Milky Way dwarf contamination. T…

Finetuning Stellar Spectra Foundation Models with LoRA

Xiaosheng Zhao, Yuan-Sen Ting, Alexander S. Szalay +1

Foundation models are beginning to impact stellar spectroscopy, where spectra encode rich physical information in a structured, language-like form. A key challenge is adapting thes…
