Bayesian at heart: Towards autonomic outflow estimation via generative state-space modelling of heart rate dynamics

1 code implementation8 Mar 2023 Fernando E. Rosas, Diego Candia-Rivera, Andrea I Luppi, Yike Guo, Pedro A. M. Mediano

Recent research is revealing how cognitive processes are supported by a complex interplay between the brain and the rest of the body, which can be investigated by the analysis of physiological features such as breathing rhythms, heart rate, and skin conductance.

Bayesian Inference Decision Making

Synergistic information supports modality integration and flexible learning in neural networks solving multiple tasks

no code implementations6 Oct 2022 Alexandra M. Proca, Fernando E. Rosas, Andrea I. Luppi, Daniel Bor, Matthew Crosby, Pedro A. M. Mediano

These findings open the door to new ways of investigating how and why learning systems employ specific information-processing strategies, and support the principle that the capacity for general-purpose learning critically relies in the system's information dynamics.

Greater than the parts: A review of the information decomposition approach to causal emergence

no code implementations12 Nov 2021 Pedro A. M. Mediano, Fernando E. Rosas, Andrea I. Luppi, Henrik J. Jensen, Anil K. Seth, Adam B. Barrett, Robin L. Carhart-Harris, Daniel Bor

Emergence is a profound subject that straddles many scientific disciplines, including the formation of galaxies and how consciousness arises from the collective activity of neurons.

Towards an extended taxonomy of information dynamics via Integrated Information Decomposition

no code implementations27 Sep 2021 Pedro A. M. Mediano, Fernando E. Rosas, Andrea I Luppi, Robin L. Carhart-Harris, Daniel Bor, Anil K. Seth, Adam B. Barrett

Complex systems, from the human brain to the global economy, are made of multiple elements that interact in such ways that the behaviour of the `whole' often seems to be more than what is readily explainable in terms of the `sum of the parts.'

Causal Discovery

Integrated information as a common signature of dynamical and information-processing complexity

no code implementations18 Jun 2021 Pedro A. M. Mediano, Fernando E. Rosas, Juan Carlos Farah, Murray Shanahan, Daniel Bor, Adam B. Barrett

The apparent dichotomy between information-processing and dynamical approaches to complexity science forces researchers to choose between two diverging sets of tools and explanations, creating conflict and often hindering scientific progress.

Learning, compression, and leakage: Minimising classification error via meta-universal compression principles

no code implementations14 Oct 2020 Fernando E. Rosas, Pedro A. M. Mediano, Michael Gastpar

Learning and compression are driven by the common aim of identifying and exploiting statistical regularities in data, which opens the door for fertile collaboration between these areas.

General Classification PAC learning

Causal blankets: Theory and algorithmic framework

no code implementations28 Aug 2020 Fernando E. Rosas, Pedro A. M. Mediano, Martin Biehl, Shamil Chandaria, Daniel Polani

We introduce a novel framework to identify perception-action loops (PALOs) directly from data based on the principles of computational mechanics.

Reconciling emergences: An information-theoretic approach to identify causal emergence in multivariate data

1 code implementation17 Apr 2020 Fernando E. Rosas, Pedro A. M. Mediano, Henrik J. Jensen, Anil. K. Seth, Adam B. Barrett, Robin L. Carhart-Harris, Daniel Bor

The broad concept of emergence is instrumental in various of the most challenging open scientific questions -- yet, few quantitative theories of what constitutes emergent phenomena have been proposed.
