Stellar parameters for ~650000 stars with APOGEE

We train a convolutional neural network, APOGEE Net, to predict Teff, logg, and, for some stars, [Fe/H], based on the APOGEE spectra. This is the first pipeline adapted for...我们基于APOGEE光谱（APOGEE spectra），训练卷积神经网络（convolutional neural network）APOGEE Net，以预测恒星的有效温度（Teff）与表面重力对数（logg），并针对部分恒星预测其金属丰度（[Fe/H]）。这是首个适配于……的处理流程。
