Sparse Recovery via $ℓ_{1}^{2} - η ℓ_{2}^{2}$ Minimization

Lang Yu, Nan-jing Huang

The weighted difference of squared norms (WDSN) penalty $ℓ_{1}^{2} - η ℓ_{2}^{2}$ with $0 \leq η \leq 1$ has attracted considerable attention due to its strong sparsity-promoting ability…

Sparse Recovery via $ℓ_{p}^{p} / ℓ_{q}^{p}$ Ratio Minimization: Theory and Algorithm

Lang Yu, Nan-jing Huang

The constrained $ℓ_{p}^{p} / ℓ_{q}^{p}$ ratio model is scale invariant and is therefore attractive for sparse signal recovery. However, its nonconvex, nonsmooth, and fractional structu…
