%description
Approaches a group sparse solution of an underdetermined linear system. It
implements the proximal gradient algorithm to solve a lower regularization
model of group sparse learning. For details, please refer to the paper "Y.
Hu, C. Li, K. Meng, J. Qin and X. Yang. Group sparse optimization via
l_{p,q} regularization. Journal of Machine Learning Research, to appear,
2017".
