The Cannon 2: Compressed sensing edition
If we take The Cannon to large numbers of labels (say chemical abundances), the model complexity grows very fast. At the same time, we know that most chemicals affect very few wavelengths in the spectrum; that is, we know that the problem is sparse. Here we use standard methods to discover and enforce sparsity.
