Approximate message passing with restricted Boltzmann machine priors

JOURNAL OF STATISTICAL MECHANICS-THEORY AND EXPERIMENT 2016年 第7期2016卷
作者: Tramel, Eric W. Dremeau, Angelique Krzakala, Florent Sorbonne Univ F-75005 Paris France Univ Paris 06 F-75005 Paris France Ecole Normale Super Lab Phys Stat UMR CNRS 8550 Rue Lhomond F-75005 Paris France ENSTA Bretagne Lab STICC UMR 6285 F-29806 Brest France
Approximate message passing (AMP) has been shown to be an excellent statistical approach to signal inference and compressed sensing problems. The AMP framework provides modularity in the choice of signal prior;here we... 详细信息

JOURNAL OF STATISTICAL MECHANICS-THEORY AND EXPERIMENT 2022年 第6期2022卷 063401-063401页
作者: Piccioli, Giovanni Semerjian, Guilhem Sicuro, Gabriele Zdeborova, Lenka Ecole Polytech Fed Lausanne SPOC Lab CH-1015 Lausanne Switzerland Sorbonne Univ Univ PSL Univ Paris Cite CNRSLab PhysEcole Normale Super F-75005 Paris France Kings Coll London London WC2R 2LS England
The problem of aligning Erdos-Renyi random graphs is a noisy, average-case version of the graph isomorphism problem, in which a pair of correlated random graphs is observed through a random permutation of their vertic... 详细信息

JOURNAL OF STATISTICAL MECHANICS-THEORY AND EXPERIMENT 2021年 第9期2021卷
作者: Okajima, Koki Kabashima, Yoshiyuki Univ Tokyo Grad Sch Sci Bunkyo Ku Tokyo 1130033 Japan
We develop a message-passing algorithm for noisy matrix completion problems based on matrix factorization. The algorithm is derived by approximating message distributions of belief propagation with Gaussian distributi... 详细信息

The cavity approach to parallel dynamics of Ising spins on a graph

JOURNAL OF STATISTICAL MECHANICS-THEORY AND EXPERIMENT 2009年 第8期2009卷 P08009-P08009页
作者: Neri, I. Bolle, D. Katholieke Univ Leuven Inst Theoret Fys B-3001 Leuven Belgium
We use the cavity method to study the parallel dynamics of disordered Ising models on a graph. In particular, we derive a set of recursive equations in single-site probabilities of paths propagating along the edges of... 详细信息

Over-parametrization was a crucial ingredient for recent developments in inference and machine-learning fields. However a good theory explaining this success is still lacking. In this paper we study a very simple case... 详细信息
