Sparse Dictionaries for Continuous-Domain Inverse Problems
Michaël Unser, Shayan Aziznejad, Thomas Jean Debarre
We study 1D continuous-domain inverse problems for multicomponent signals. The prior assumption on these signals is that each component is sparse in a different dictionary specified by a regularization operators. We introduce a hybrid regularization functi ...
2019Secure numerical and logical multi party operations
We derive algorithms for efficient secure numerical and logical operations in the semi-honest model ensuring statistical or perfect security for secure multi-party computation (MPC). To derive our algorithms for trigonometric functions, we use basic mathem ...
Elsevier Science Bv2017Bounds for Pach's Selection Theorem and for the Minimum Solid Angle in a Simplex
We estimate the selection constant in the following geometric selection theorem by Pach: For every positive integer d, there is a constant such that whenever are n-element subsets of , we can find a point and subsets for every , each of size at least , suc ...
Springer2015Extendability of Continuous Maps Is Undecidable
We consider two basic problems of algebraic topology: the extension problem and the computation of higher homotopy groups, from the point of view of computability and computational complexity. The extension problem is the following: Given topological space ...
