Near Optimal Signal Recovery From Random Projections: Universal Encoding Strategies?
, 2004
"... Suppose we are given a vector f in RN. How many linear measurements do we need to make about f to be able to recover f to within precision ɛ in the Euclidean (ℓ2) metric? Or more exactly, suppose we are interested in a class F of such objects— discrete digital signals, images, etc; how many linear m ..."

Universality classes for horizon instabilities
, 2003
"... Abstract: We introduce a notion of universality classes for the GregoryLaflamme instability and determine, in the supergravity approximation, the stability of a variety of solutions, including the nonextremal D3brane, M2brane, and M5brane. These three nondilatonic branes cross over from instab ..."

Raptor codes
 IEEE Transactions on Information Theory

"... LTCodes are a new class of codes introduced in [1] for the purpose of scalable and faulttolerant distribution of data over computer networks. In this paper we introduce Raptor Codes, an extension of LTCodes with linear time encoding and decoding. We will exhibit a class of universal Raptor codes: ..."

The Universality Class Of The Electroweak Theory
, 1998
"... We study the universality class and critical properties of the electroweak theory at finite temperature. Such critical behaviour is found near the endpoint mH = mH;c of the line of first order electroweak phase transitions in a wide class of theories, including the Standard Model (SM) and a part of ..."

The KosterlitzThouless universality class
 Nucl. Phys. B
, 1997
"... We examine the Kosterlitz–Thouless universality class and show that conventional (essential) scaling at this type of phase transition is self–consistent only if modified by multiplicative logarithmic corrections. In the case of specific heat these logarithmic corrections are identified analytically. ..."

, 1993
"... Abstract. In this paper we study quantum computation from a complexity theoretic viewpoint. Our first result is the existence of an efficient universal quantum Turing machine in Deutsch’s model of a quantum Turing machine (QTM) [Proc. Roy. Soc. London Ser. A, 400 (1985), pp. 97–117]. This constructi ..."

Loopy belief propagation for approximate inference: An empirical study. In:
 Proceedings of Uncertainty in AI,
, 1999
"... Abstract Recently, researchers have demonstrated that "loopy belief propagation" the use of Pearl's polytree algorithm in a Bayesian network with loops can perform well in the context of errorcorrecting codes. The most dramatic instance of this is the near Shannonlimit performanc ..."

nothing directly to do with coding or decoding will show that in some sense belief propagation "converges with high probability to a nearoptimum value" of the desired belief on a class of loopy DAGs Progress in the analysis of loopy belief propagation has been made for the case of networks
Universality classes in nonequilibrium lattice systems

Universality classes for extremevalue statistics

"... The equilibrium lowtemperature physics of disordered systems is governed by the statistics of extremely lowenergy states. It is thus relevant to discuss the possible universality classes for extremevalue statistics. We compare the usual probabilistic classification to the results of the replica ..."
