Generalized Sampling with Structural Constraints
نویسندگان
چکیده
We consider a generalized sampling scheme, for finite-dimensional sampling and reconstruction spaces where the correcting transformation must satisfy certain structural constraints. Several criteria are considered, which aim to minimize the squared error norm between the input signal and its approximation within the reconstruction space. By restricting the correcting transformation to a desired form, it is possible to obtain efficient implementations of the correction stage which may be vital in real time applications.

Duality for vector equilibrium problems with constraints
In the paper, we study duality for vector equilibrium problems using a concept of generalized convexity in dealing with the quasi-relative interior. Then, their applications to optimality conditions for quasi-relative efficient solutions are obtained. Our results are extensions of several existing ones in the literature when the ordering cones in both the objective space and the constr...
متن کاملRandom Sampling with Removal
Random sampling is a classical tool in constrained optimization. Under favorable conditions, the optimal solution subject to a small subset of randomly chosen constraints violates only a small subset of the remaining constraints. Here we study the following variant that we call random sampling with removal: suppose that after sampling the subset, we remove a fixed number of constraints from the...
متن کاملCompressive optical interferometry under structural constraints.
Compressive sensing (CS) combines data acquisition with compression coding to reduce the number of measurements required to reconstruct a sparse signal. In optics, this usually takes the form of projecting the field onto sequences of random spatial patterns that are selected from an appropriate random ensemble. We show here that CS can be exploited in 'native' optics hardware without introducin...
متن کاملEla Symmetric Inverse Generalized Eigenvalue Problem with Submatrix Constraints in Structural Dynamic Model Updating
In this literature, the symmetric inverse generalized eigenvalue problem with submatrix constraints and its corresponding optimal approximation problem are studied. A necessary and sufficient condition for solvability is derived, and when solvable, the general solutions are presented.
