Granger causality vs. dynamic Bayesian network inference: a comparative study [PDF]

open access: yesBMC Bioinformatics, 2009
Background In computational biology, one often faces the problem of deriving the causal relationship among different elements such as genes, proteins, metabolites, neurons and so on, based upon multi-dimensional temporal data.

Bayesian Nonparametrics for Sparse Dynamic Networks

open access: yes, 2023
In this paper we propose a Bayesian nonparametric approach to modelling sparse time-varying networks. A positive parameter is associated to each node of a network, which models the sociability of that node. Sociabilities are assumed to evolve over time, and are modelled via a dynamic point process model. The model is able to capture long term evolution

Dynamic Network Security Analysis Based on Bayesian Attack Graphs [PDF]

open access: yesJisuanji kexue, 2022
In order to overcome the difficulties that current attack graph model cannot reflect real-time network attack events,a method is proposed including a forward risk probability update algorithm and a forward-backward combined risk probability update ...

Relational Dynamic Bayesian Networks

open access: yesJournal of Artificial Intelligence Research, 2005
Stochastic processes that involve the creation of objects and relations over time are widespread, but relatively poorly studied. For example, accurate fault diagnosis in factory assembly processes requires inferring the probabilities of erroneous assembly operations, but doing this efficiently and accurately is difficult.

Asynchronous Dynamic Bayesian Networks

open access: yesCoRR, 2012
Systems such as sensor networks and teams of autonomous robots consist of multiple autonomous entities that interact with each other in a distributed, asynchronous manner. These entities need to keep track of the state of the system as it evolves.

Bayesian Inference of Stochastic Dynamical Networks

open access: yesCoRR, 2022
Network inference has been extensively studied in several fields, such as systems biology and social sciences. Learning network topology and internal dynamics is essential to understand mechanisms of complex systems. In particular, sparse topologies and stable dynamics are fundamental features of many real-world continuous-time (CT) networks.

A DBN-DEVS Extension for Modeling and Simulate Uncertain Systems

open access: yesApplied Artificial Intelligence, 2021
In this paper, our goal is to propose a new extension to the Discrete Event System (DEVS) formalism, which is based on Dynamic Bayesian Network (DBN), and this extension will be called DBN-DEVS, which allows to modeling and simulate the uncertain ...
