摘要:

本文推导了连续变量高斯模型上的循环校正置信传播方程。利用高斯模型的置信传播平均值的精确性,基于腔图上的置信传播,找到了一种不同的获得协方差的方法。我们讨论了这种循环校正算法的期望传播算法的情况下,该模型不再是高斯,但略有扰动的非线性项。

英文摘要:

In this paper we derive the equations for Loop Corrected Belief Propagation on a continuous variable Gaussian model. Using the exactness of the averages for belief propagation for Gaussian models, a different way of obtaining the covariances is found, based on Belief Propagation on cavity graphs. We discuss the relation of this loop correction algorithm to Expectation Propagation algorithms for the case in which the model is no longer Gaussian, but slightly perturbed by nonlinear terms.
