Complexity-Regularized Image Denoising
We develop a new approach to image denoising based on complexity regularization. This technique presents a flexible alternative to the more conventional l2 , l1 , and Besov regula...

ICA Using Kernel Entropy Estimation with NlogN Complexity
Abstract. Mutual information (MI) is a common criterion in independent component analysis (ICA) optimization. MI is derived from probability density functions (PDF). There are scen...

Design and Implementation of a Radix-4 Complex Division Unit with Prescaling
—We present a design and implementation of a radix-4 complex division unit with prescaling of the operands. Specifically, we extend the treatment of the residual bound and error...

Reasoning about soft constraints and conditional preferences: complexity results and approximation techniques
Many real life optimization problems contain both hard and soft constraints, as well as qualitative conditional preferences. However, there is no single formalism to specify all t...
