【Title】Beyond integrated information: Information dynamics in multivariate dynamical systems
【Abstract】
Research on foundational questions concerning topics like agency, consciousness, and self-organisation typically focuses on the study of functional organisation -- how the interactions between different components of a system give rise to rich information dynamics. Two prominent frameworks to study information dynamics in complex systems are the Partial Information Decomposition (PID) framework, and Integrated Information Theory (IIT), both extensions of Shannon's theory of information. In this talk we will present a novel tool in information dynamics, Integrated Information Decomposition (ΦID), that results from the unification of IIT and PID. We show how ΦID paves the way for more detailed analyses of interdependencies in multivariate time series, and sheds light on collective modes of information dynamics that have not been previously reported. Additionally, ΦID reveals that what is typically referred to as ‘integration’ is actually an aggregate of several heterogeneous phenomena. Finally, to ground the concepts of PID and ΦID, we present a novel measure of synergy with a concrete operational meaning, that can be readily extended to form what is, to the best of our knowledge, the first operational measure of integrated information. Together, these two contributions provide valuable tools to formulate and test theories of emergence, agency, and self-organisation in complex systems.
