Factor Graphs and the Sum-Product Algorithm

by Frank R. Kschischang, Brendan J. Frey, Hans-Andrea Loeliger - IEEE TRANSACTIONS ON INFORMATION THEORY , 1998
"... A factor graph is a bipartite graph that expresses how a "global" function of many variables factors into a product of "local" functions. Factor graphs subsume many other graphical models including Bayesian networks, Markov random fields, and Tanner graphs. Following one simple c ..."

Constructing Free Energy Approximations and Generalized Belief Propagation Algorithms

by Jonathan S. Yedidia, William T. Freeman, Yair Weiss - IEEE Transactions on Information Theory , 2005
"... Important inference problems in statistical physics, computer vision, error-correcting coding theory, and artificial intelligence can all be reformulated as the computation of marginal probabilities on factor graphs. The belief propagation (BP) algorithm is an efficient way to solve these problems t ..."

On factor graphs and the Fourier transform

by Yongyi Mao, Frank R. Kschischang - IN IEEE TRANS. INFORM. THEORY , 2005
"... We introduce the concept of convolutional factor graphs, which represent convolutional factorizations of multivariate functions, just as conventional (multiplicative) factor graphs represent multiplicative factorizations. Convolutional and multiplicative factor graphs arise as natural Fourier trans ..."

Some Remarks on Factor Graphs

by Hans-andrea Loeliger - Proc. 3rd Int. Symp. on Turbo Codes and Related Topics , 2003
"... The paper is a collection of remarks, some rather plain, on various issues with factor graphs. In particular, it is pointed out that powerful signal processing techniques such as gradient methods, Kalman filtering, and the particle filter can be used and combined in factor graphs. ..."

Normal Factor Graphs

by Ali Al-bashabsheh , 2014
"... This thesis introduces normal factor graphs under a new semantics, namely, the exterior function semantics. Initially, this work was motivated by two distinct lines of re-search. One line is “holographic algorithms,” a powerful approach introduced by Valiant for solving various counting problems in ..."

Factor-Graph Algorithms for Equalization

by Robert J. Drost, Andrew C. Singer , 2007
"... In this paper, we use the factor-graph framework to describe the statistical relationships that arise in the equalization of data transmitted over an intersymbol interference channel, and use it to develop several new algorithms for linear and decision feedback approaches. Specifically, we examine b ..."
