Tensor networks contraction and the belief propagation algorithm
Physical Review Research, 2021 Belief propagation is a well-studied message-passing algorithm that runs over graphical models and can be used for approximate inference and approximation of local marginals.

Graph Belief Propagation Networks
CoRR, 2021 With the wide-spread availability of complex relational data, semi-supervised node classification in graphs has become a central machine learning problem. Graph neural networks are a recent class of easy-to-train and accurate methods for this problem that map the features in the neighborhood of a node to its label, but they ignore label correlation ...

Generalized Belief Propagation Algorithms for Decoding of Surface Codes [PDF]
Quantum, 2023 Belief propagation (BP) is well-known as a low complexity decoding algorithm with a strong performance for important classes of quantum error correcting codes, e.g.

CoRR, 2012 A major benefit of graphical models is that most knowledge is captured in the model structure. Many models, however, produce inference problems with a lot of symmetries not reflected in the graphical structure and hence not exploitable by efficient inference techniques such as belief propagation (BP).

Belief Propagation With Permutated Graphs of Polar Codes
IEEE Access, 2020 The belief propagation (BP) decoding of polar codes provides better bit error rate (BER) and packet error rate (PER) performance than the successive cancelation (SC) decoding.

Belief Propagation Bit-Flip Decoder for Polar Codes
IEEE Access, 2019 The bit-flip method has been successfully applied to the successive cancellation (SC) decoder to improve the block error rate (BLER) performance for polar codes in the finite code length region.

Homography-guided stereo matching for wide-baseline image interpolation
Computational Visual Media, 2021 Image interpolation has a wide range of applications such as frame rate-up conversion and free viewpoint TV. Despite significant progresses, it remains an open challenge especially for image pairs with large displacements. In this paper, we first propose

Belief Propagation for Panorama Generation [PDF]
Third International Symposium on 3D Data Processing, Visualization, and Transmission (3DPVT'06), 2006 We present an algorithm for generating panoramic images of complex scenes from a multi-sensor camera. We further present a programmable graphics hardware implementation to process the large data sets more quickly. Because the sensors do not share the same center of projection, nearby objects may not be properly aligned, creating a ghosting or echoing ...
