Multiscale Granger causality [PDF]

open access: yesPhysical Review E, 2017
In the study of complex physical and biological systems represented by multivariate stochastic processes, an issue of great relevance is the description of the system dynamics spanning multiple temporal scales. While methods to assess the dynamic complexity of individual processes at different time scales are well-established, multiscale analysis of ...

New considerations on the validity of the Wiener-Granger causality test

open access: yesHeliyon, 2020
The Wiener-Granger causality test is used to predict future experimental results from past observations in a purely mathematical way. For instance, in many scientific papers this test has been used to study the causality relations in the case of neuronal

DLI: A Deep Learning-Based Granger Causality Inference

open access: yesComplexity, 2020
Integrating autoencoder (AE), long short-term memory (LSTM), and convolutional neural network (CNN), we propose an interpretable deep learning architecture for Granger causality inference, named deep learning-based Granger causality inference (DLI).

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

open access: yes, 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.

Identifying interactions in the time and frequency domains in local and global networks : a Granger causality approach [PDF]

open access: yes, 2010
Background Reverse-engineering approaches such as Bayesian network inference, ordinary differential equations (ODEs) and information theory are widely applied to deriving causal relationships among different elements such as genes, proteins, metabolites,

The Relation between Granger Causality and Directed Information Theory: A Review

open access: yesEntropy, 2012
This report reviews the conceptual and theoretical links between Granger causality and directed information theory. We begin with a short historical tour of Granger causality, concentrating on its closeness to information theory.
