This is the code associated with The Cannon, a data-driven method for determining stellar labels (physical parameters and chemical abundances) from stellar spectra in the context of large spectroscopic surveys. It closely follows the method outlined in Ness et al. 2015, although some minor changes have been made. A description of these changes is outlined in Ho et al. 2016 (arXiv:1602.00303).

Documentation for The Cannon can be found here.
