Investigating High-Order Behaviors in Multivariate Cardiovascular Interactions via Nonlinear Prediction and Information-Theoretic Tools
Chiara Barà, Yuri Antonacci, Laura Sparacino +4
Assessing the synergistic high-order behaviors (HOBs) that emerge from underlying structural mechanisms is crucial to characterize complex systems. This work leverages the combined…
Localizing synergies of hidden factors across complex systems: resting brain networks and HeLa gene expression profile as case studies
Marlis Ontivero-Ortega, Gorana Mijatovic, Luca Faes +2
Factor analysis is a well-known statistical method to describe the variability of observed variables in terms of a smaller number of unobserved latent variables called factors. Eve…
Local Granger Causality
Sebastiano Stramaglia, Tomas Scagliarini, Yuri Antonacci +1
Granger causality is a statistical notion of causal influence based on prediction via vector autoregression. For Gaussian variables it is equivalent to transfer entropy, an informa…
Multiscale Granger causality analysis by à trous wavelet transform
Sebastiano Stramaglia, Iege Bassez, Luca Faes +1
Since interactions in neural systems occur across multiple temporal scales, it is likely that information flow will exhibit a multiscale structure, thus requiring a multiscale gene…
Synergy and redundancy in the Granger causal analysis of dynamical networks
Sebastiano Stramaglia, Jesus M. Cortes, Daniele Marinazzo
We analyze by means of Granger causality the effect of synergy and redundancy in the inference (from time series data) of the information flow between subsystems of a complex netwo…
Expanding the Transfer Entropy to Identify Information Subgraphs in Complex Systems
S. Stramaglia, Guo-Rong Wu, M. Pellicoro +1
We propose a formal expansion of the transfer entropy to put in evidence irreducible sets of variables which provide information for the future state of each assigned target. Multi…
Redundant variables and Granger causality
L. Angelini, M. de Tommaso, D. Marinazzo +3
We discuss the use of multivariate Granger causality in presence of redundant variables: the application of the standard analysis, in this case, leads to under-estimation of causal…
