Image Denoising using Shiftable Directional Pyramid and Scale Mixtures of Complex Gaussians
— In this paper, a modified version of the complex directional pyramid (PDTDFB) is proposed. Unlike the previous approach, the new FB provides an approximately tight-frame decom...

A Separation of NP and coNP in Multiparty Communication Complexity
: We prove that coNP MA in the number-on-forehead model of multiparty communication complexity for up to k = (1 - )logn players, where > 0 is any constant. Specifically, we con...

Characterizing Valiant's algebraic complexity classes
Valiant introduced 20 years ago an algebraic complexity theory to study the complexity of polynomial families. The basic computation model used is the arithmetic circuit, which ma...
