Stellar Parameterization of LAMOST M Dwarf Stars

M dwarf stars are the most common in Galaxy, dominating population of Galaxy by numbers at faint magnitudes. Precise and accurate stellar parameters for dwarfs crucial importance many studies. However, atmospheric difficult to be determined. In this paper, we present a catalog spectroscopic ($T_{eff}$ [M/H]) $\sim$ 300,000 observed both LAMOST Gaia using Stellar Label Machine (SLAM). We train SLAM model spectra with APOGEE Data Release 16 (DR16) labels $2800 \lt T_{eff} 4500$K $-2 [M/H] 0.5$ dex. The $T_{eff}$ is agreement within $\sim 50$K compared previous study determined observation, agree 0.12 dex observation. also set up trained BT-Settl model, random uncertainties (in cross-validation) 60K 90$K study.
