[1206.0976] Loopy Belief Propagation in Bayesian

2012-6-6  In this paper we present a synthesis of the work performed on two inference algorithms: the Pearl's belief propagation (BP) algorithm applied to Bayesian networks without loops (i.e. polytree) and the Loopy belief propagation (LBP) algorithm (inspired from the BP) which is applied to networks containing undirected cycles. It is known that the BP algorithm, applied

Review for NeurIPS paper: Belief Propagation Neural

Review 2. Summary and Contributions: This paper generalizes Loopy Belief Propagation (LBP) on factor graphs by augmenting the architecture with learnable neural operators that are used to compute the aggregated factor-to-node messages.The paper proves some desirable properties that guarantee exact results on loop-free factor graphs. The effectiveness of the proposed

In this work, we propose BP-MVSNet, a convolutional neural network (CNN)-based Multi-View-Stereo (MVS) method that uses a differentiable Conditional Random Field (CRF) layer for regularization. To this end, we propose to extend the BP layer and add what is necessary to successfully use ...

Belief Propagation Neural Networks

introduce belief propagation neural networks (BPNNs), a class of parameterized operators that operate on factor graphs and generalize Belief Propagation (BP). In its strictest form, a BPNN layer (BPNN-D) is a learned iterative operator that provably maintains many of the desirable properties of BP for any choice of the parameters.

The algorithm avoids the conflicts carefully by building direct paths among different layers for every code bit, when all the layers are processed in a parallel way. With such paths, every variable is able to be updated layer by layer. As a result, the PLBP algorithm can get the same error
