Calibration of distances with deep learning

Gaia measures the five astrometric parameters for stars in the Milky Way, but only four of them (positions and proper motion, but not distance) are well measured beyond a few...盖亚卫星（Gaia）能够对银河系内的恒星开展五项天体测量参数的测定工作，然而其中仅有四项——即恒星位置与自行，不包含距离参数——可在绝大多数天体中实现高精度测量……
