Belief Propagation Algorithm for Portfolio Optimization Problems. [PDF]

open access: yesPLoS ONE, 2015
The typical behavior of optimal solutions to portfolio optimization problems with absolute deviation and expected shortfall models using replica analysis was pioneeringly estimated by S. Ciliberti et al. [Eur. Phys. B. 57, 175 (2007)]; however, they have

Higher-Order Belief Propagation Correction Decoder for Polar Codes [PDF]

open access: yesEntropy, 2022
Belief propagation (BP) decoding for polar codes has been extensively studied because of its inherent parallelism. However, its performance remains inferior to that of successive cancellation list decoding (SCL) due to the structure of the decoding graph.

Belief propagation in monoidal categories [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2014
We discuss a categorical version of the celebrated belief propagation algorithm. This provides a way to prove that some algorithms which are known or suspected to be analogous, are actually identical when formulated generically. It also highlights the

The graphical brain: Belief propagation and active inference [PDF]

open access: yesNetwork Neuroscience, 2017
This paper considers functional integration in the brain from a computational perspective. We ask what sort of neuronal message passing is mandated by active inference—and what implications this has for context-sensitive connectivity at microscopic and ...

Event-Based Stereo Depth Estimation Using Belief Propagation [PDF]

open access: yesFrontiers in Neuroscience, 2017
Compared to standard frame-based cameras, biologically-inspired event-based sensors capture visual information with low latency and minimal redundancy. These event-based sensors are also far less prone to motion blur than traditional cameras, and still ...

Kernel Belief Propagation [PDF]

open access: yes, 2011
We propose a nonparametric generalization of belief propagation, Kernel Belief Propagation (KBP), for pairwise Markov random fields. Messages are represented as functions in a reproducing kernel Hilbert space (RKHS), and message updates are simple linear operations in the RKHS.

An Enhanced Belief Propagation Flipping Decoder for Polar Codes with Stepping Strategy [PDF]

open access: yesEntropy, 2022
The Belief Propagation (BP) algorithm has the advantages of high-speed decoding and low latency. To improve the block error rate (BLER) performance of the BP-based algorithm, the BP flipping algorithm was proposed.

Adaptive Learned Belief Propagation for Decoding Error-Correcting Codes [PDF]

open access: yesEntropy
Weighted belief propagation (WBP) for the decoding of linear block codes is considered. In WBP, the Tanner graph of the code is unrolled with respect to the iterations of the belief propagation decoder.

Quantum Belief Propagation

open access: yes, 2007
We present an accurate numerical algorithm, called quantum belief propagation (QBP), for simulation of one-dimensional quantum systems at non-zero temperature. The algorithm exploits the fact that quantum effects are short-range in these systems at non-zero temperature, decaying on a length scale inversely proportional to the temperature. We compare to
