Stellar age determination using deep NN

Recent spectroscopic surveys provide element abundances for large samples of Milky Way stars, from which stellar parameters can be inferred. Stellar ages, among them, are both a...近年开展的光谱巡天观测（spectroscopic surveys）为大量银河系（Milky Way）恒星样本提供了元素丰度（element abundances）数据，依托此类数据可推演出各类恒星参数（stellar parameters）。其中，恒星年龄（stellar ages）既是
