Bayesian Networks in Radiology. [PDF]

open access: yesRadiol Artif Intell, 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 Approach to Linear Bayesian Networks

open access: yesCoRR, 2023
This study proposes the first Bayesian approach for learning high-dimensional linear Bayesian networks. The proposed approach iteratively estimates each element of the topological ordering from backward and its parent using the inverse of a partial covariance matrix.

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 Flow Networks

open access: yesCoRR, 2023
This paper introduces Bayesian Flow Networks (BFNs), a new class of generative model in which the parameters of a set of independent distributions are modified with Bayesian inference in the light of noisy data samples, then passed as input to a neural network that outputs a second, interdependent distribution.

Data-Driven Bayesian Network Learning: A Bi-Objective Approach to Address the Bias-Variance Decomposition

open access: yesMathematical and Computational Applications, 2020
We present a novel bi-objective approach to address the data-driven learning problem of Bayesian networks. Both the log-likelihood and the complexity of each candidate Bayesian network are considered as objectives to be optimized by our proposed ...

Feature Dynamic Bayesian Networks [PDF]

open access: yes, 2008
Feature Markov Decision Processes (PhiMDPs) are well-suited for learning agents in general environments. Nevertheless, unstructured (Phi)MDPs are limited to relatively simple environments.

High-Dimensional Bayesian Network Inference From Systems Genetics Data Using Genetic Node Ordering

open access: yesFrontiers in Genetics, 2019
Studying the impact of genetic variation on gene regulatory networks is essential to understand the biological mechanisms by which genetic variation causes variation in phenotypes. Bayesian networks provide an elegant statistical approach for multi-trait

A Probability-based Evolutionary Algorithm with Mutations to Learn Bayesian Networks

open access: yesInternational Journal of Interactive Multimedia and Artificial Intelligence, 2014
Bayesian networks are regarded as one of the essential tools to analyze causal relationship between events from data. To learn the structure of highly-reliable Bayesian networks from data as quickly as possible is one of the important problems that ...
