LAMOST DR10

Large Sky Area Multi-Object Fiber Spectroscopic Telescope Data Release 10. Largest spectroscopic survey before DESI. Transfer-learning run exposed training set bias.

QC CAUTION

11.4M spectra

44,075 anomalies (0.39%)

Optical spectroscopy (3700-9100 Å)

LAMOST

~56% B-dominant cross-transfer (empirical; the 98% figure was a synthetic schematic not a measurement). Native retrain reduces anomaly count 21.4x (43,915 -> 2,054 at S>5). Path-C native model in progress.
