摘要

We consider L_1-regularization of spectrally constrained DOT. Three popular algorithms are investigated: itera-tively reweighted least square algorithm (IRLS), alternating directional method of multipliers (ADMM) and fast iterative shrinkage-thresholding algorithm (FISTA). We evaluate different regularizers and algorithms on a 3D simulated multi-spectral example.
