Nonequilibrium thermodynamics of the asymmetric Sherrington-Kirkpatrick model

Our new paper nonequilibrium thermodynamics of large, disordered networks - in collaboration with Masanao Igarashi and Hideaki Shimazaki - has just been published in Nature Communications. In this study we analytically calculate an exact expression for the entropy production of an asymmetric version of the Sherrington-Kirkpatric model, finding that it is maximized both...  Read more

Ikerbasque Research Fellow position

I’m thrilled to announce that I’m starting a new position as an Ikerbasque Research Fellow at the Basque Center for Applied Mathematics, where I will join the Mathematical, Computational and Experimental Neuroscience team.

I’m really excited to start this new period in ...  Read more

How particular is the physics of the free energy principle?

In a new paper in Physics of Life Reviews I present a deep mathematical exploration of the free energy principle (FEP) in collaboration with Beren Millidge, Alexander Tschantz and Chris Buckley. The FEP has gained an important momentum as an ambitious theory aiming to provide a unifying theory of mind and life, explained in terms of approximate Bayesian i...  Read more

A unifying framework for mean-field theories of asymmetric kinetic Ising systems

I’m happy to see published this new paper in collaboration with Amin Moosavi and Hideaki Shimazaki in Nature Communications. In this paper study and unify different kinetic mean-field methods in Ising models with the objective of developing tools for studying large data-sets from networks of neurons in non-equilibrium conditions and near critical and maximally fluctuating regimes. We propose a framework that integrates previo...  Read more

Critical integration in neural and cognitive systems: Beyond power-law scaling as the hallmark of soft assembly

I just published a new paper with Ezequiel Di Paolo in Neuroscience & Biobehavioral Reviews. Here we review the link of self-organized criticality and integrated information with ideas about soft assembly in neural and cognitive process. Studying the properties of power-law scaling processes as a in indicator of properties like soft-assembly, self-organization or interaction-dominant-dynamics is a suggest...  Read more

DIMENSIVE project

I’m happy to share that I have been granted a MSCA-IF grant to start a project at the University of Sussex in collaboration with Chris Buckley. The project aims to apply information-theoretic and inference methods to develop models of neural activity from zebrafish larvae in closed loop behavior, e.g. trying ...  Read more

Scaling Behaviour and Critical Phase Transitions in Integrated Information Theory

I just published a new paper exploring some of the ideas we initiated in our Integrated information in the thermodynamic limit (Aguilera & Di Paolo, 2019) paper. Here, I explore in detail many of the assumptions of Integrated Information Theory (specifically IIT 3.0) by computing integration in large kinetic Ising networks presenting a critical point. By combining a simpl...  Read more
