Texture synthesis via a noncausal nonparametric multiscale Markov random field
Abstract— Our noncausal, nonparametric, multiscale, Markov random field (MRF) model is capable of synthesising and capturing the characteristics of a wide variety of textures, f...

Random unary predicates: Almost sure theories and countable models
Let Un,p be the random unary predicate and Tk the almost sure first-order theory of Un,p under the linear ordering, where k is a positive integer and n−1/k p(n) n−1/(k+1) . F...

A characterization of c.e. random reals
A real is computably enumerable if it is the limit of a computable, increasing, converging sequence of rationals. A real is random if its binary expansion is a random sequence. Ou...

Sharing Random Bits with No Process Coordination
We present a method by which any polynomial-time randomized distributed algorithm is transformed in such way that each participating process needs only polylog local random bits a...
