Demixing Sparse Signals from Nonlinear Observations using Generalized Non-convex Regularization
Raziyeh Takbiri
We consider the recovery of a pair of sparse vectors from a limited number of nonlinear observations of their superposition: $y_i=g(\inner{\ba_i}{\bPhi\bw^\ast+\bPsi\bz^\ast})+e_i$…

Distribution-aware Analysis Minimization
Raziyeh Takbiri, Sajad Daei
This work is about recovering an analysis-sparse vector, i.e. sparse vector in some transform domain, from under-sampled measurements. In real-world applications, there often exist…
