Testing Bayesian Networks [PDF]

open access: yesIEEE Transactions on Information Theory, 2020
This work initiates a systematic investigation of testing high-dimensional structured distributions by focusing on testing Bayesian networks -- the prototypical family of directed graphical models. A Bayesian network is defined by a directed acyclic graph, where we associate a random variable with each node.

Semiparametric Bayesian networks

open access: yesInformation Sciences, 2022
We introduce semiparametric Bayesian networks that combine parametric and nonparametric conditional probability distributions. Their aim is to incorporate the advantages of both components: the bounded complexity of parametric models and the flexibility of nonparametric ones.

Bayesian Networks in Radiology [PDF]

open access: yesRadiology: Artificial Intelligence, 2023
A Bayesian network is a graphical model that uses probability theory to represent relationships among its variables. The model is a directed acyclic graph whose nodes represent variables, such as the presence of a disease or an imaging finding. Connections between nodes express causal influences between variables as probability values.

Bayesian Neural Networks [PDF]

open access: yes, 2022
In recent times, neural networks have become a powerful tool for the analysis of complex and abstract data models. However, their introduction intrinsically increases our uncertainty about which features of the analysis are model-related and which are due to the neural network.

Bayesian Networks in Reliability [PDF]

open access: yesReliability Engineering & System Safety, 2007
Over the last decade, Bayesian networks (BNs) have become a popular tool for modeling many kinds of statistical problems. We have also seen a growing interest for using BNs in the reliability analysis community. This article discusses the properties of the modeling framework that are of highest importance for reliability practitioners. Keywords:

Loop amplitudes from precision networks

open access: yesSciPost Physics Core, 2023
Evaluating loop amplitudes is a time-consuming part of LHC event generation. For di-photon production with jets we show that simple, Bayesian networks can learn such amplitudes and model their uncertainties reliably.

A cloud Bayesian network approach to situation assessment of scouting underwater targets with fixed‐wing patrol aircraft

open access: yesCAAI Transactions on Intelligence Technology, 2023
The battlefield situation changes rapidly because underwater targets' are concealment and the sea environment is uncertain. So, a great number of situation information greatly increase, which need to be dealt with in the course of scouting underwater ...

Hybrid Optimization Algorithm for Bayesian Network Structure Learning

open access: yesInformation, 2019
Since the beginning of the 21st century, research on artificial intelligence has made great progress. Bayesian networks have gradually become one of the hotspots and important achievements in artificial intelligence research.
