Theoretical Validation of the Latent Optimally Partitioned-${\ell }_2/{\ell }_1$ Penalty with Application to Angular Power Spectrum Estimation

Hiroki Kuroda, Renato Luis Garrido Cavalcante, Masahiro Yukawa

This paper demonstrates that, in both theory and practice, the latent optimally partitioned (LOP)-${\ell }_2/{\ell }_1$ penalty is effective for exploiting block-sparsity without knowled…
