Information dynamics of brain–heart physiological networks during sleep

open access: yesNew Journal of Physics, 2014
This study proposes an integrated approach, framed in the emerging fields of network physiology and information dynamics, for the quantitative analysis of brain–heart interaction networks during sleep. With this approach, the time series of cardiac vagal

Measuring High-Order Interactions in Rhythmic Processes Through Multivariate Spectral Information Decomposition

open access: yesIEEE Access, 2021
Many complex systems in physics, biology and engineering are modeled as dynamical networks and described using multivariate time series analysis. Recent developments have shown that the emergent dynamics of a network system are significantly affected by ...

Multiscale Information Decomposition: Exact Computation for Multivariate Gaussian Processes

open access: yesEntropy, 2017
Exploiting the theory of state space models, we derive the exact expressions of the information transfer, as well as redundant and synergistic transfer, for coupled Gaussian processes observed at multiple temporal scales.

Learning and Consolidation as Re-representation: Revising the Meaning of Memory

open access: yesFrontiers in Psychology, 2019
In this Hypothesis and Theory paper, we consider the problem of learning deeply structured knowledge representations in the absence of predefined ontologies, and in the context of long-term learning.

Time-varying information measures: an adaptive estimation of information storage with application to brain-heart interactions

open access: yesFrontiers in Network Physiology, 2023
Network Physiology is a rapidly growing field of study that aims to understand how physiological systems interact to maintain health. Within the information theory framework the information storage (IS) allows to measure the regularity and predictability

Optimal dynamic information provision [PDF]

open access: yesGames and Economic Behavior, 2017
We study a dynamic model of information provision. A state of nature evolves according to a Markov chain. An informed advisor decides how much information to provide to an uninformed decision maker, so as to influence his short-term decisions. We deal with a stylized class of situations, in which the decision maker has a risky action and a safe action,

Moving Frames of Reference, Relativity and Invariance in Transfer Entropy and Information Dynamics

open access: yesEntropy, 2013
We present a new interpretation of a local framework for informationdynamics, including the transfer entropy, by defining a moving frame of reference for theobserver of dynamics in lattice systems. This formulation is inspired by the idea ofinvestigating
