Quantifying Spacetime Integration across a Partition with Synergy
Virgil Griffith
In service to the mathematical underpinnings of the Information Integration Theory of Consciousness (IIT), we introduce four principled measures of integration based on the partial…
The darkweb: a social network anomaly
Kevin P. O'Keeffe, Virgil Griffith, Yang Xu +2
We analyse the darkweb and find its structure is unusual. For example, of darkweb sites \emph{never} link to another site. To call the darkweb a "web" is thus a misno…
Casper the Friendly Finality Gadget
Vitalik Buterin, Virgil Griffith
We introduce Casper, a proof of stake-based finality system which overlays an existing proof of work blockchain. Casper is a partial consensus mechanism combining proof of stake al…
Graph Theoretic Properties of the Darkweb
Virgil Griffith, Yang Xu, Carlo Ratti
We collect and analyze the darkweb (a.k.a. the "onionweb") hyperlink graph. We find properties highly dissimilar to the well-studied world wide web hyperlink graph; for example, ou…
Synergy, Redundancy and Common Information
Pradeep Kr. Banerjee, Virgil Griffith
We consider the problem of decomposing the total mutual information conveyed by a pair of predictor random variables about a target random variable into redundant, unique and syner…
Quantifying Redundant Information in Predicting a Target Random Variable
Virgil Griffith, Tracey Ho
This paper considers the problem of defining a measure of redundant information that quantifies how much common information two or more random variables specify about a target rand…
Is Consciousness Computable? Quantifying Integrated Information Using Algorithmic Information Theory
Phil Maguire, Philippe Moser, Rebecca Maguire +1
In this article we review Tononi's (2008) theory of consciousness as integrated information. We argue that previous formalizations of integrated information (e.g. Griffith, 2014) d…
A Principled Infotheoretic ϕ-like Measure
Virgil Griffith
Integrated information theory is a mathematical, quantifiable theory of conscious experience. The linchpin of this theory, the measure, quantifies a system's irreducibility to…
Irreducibility is Minimum Synergy Among Parts
Virgil Griffith, Jonathan Harel
For readers already familiar with Partial Information Decomposition (PID), we show that PID's definition of synergy enables quantifying at least four different notions of irreducib…
Intersection Information based on Common Randomness
Virgil Griffith, Edwin K. P. Chong, Ryan G. James +2
The introduction of the partial information decomposition generated a flurry of proposals for defining an intersection information that quantifies how much of "the same information…
Quantifying synergistic mutual information
Virgil Griffith, Christof Koch
Quantifying cooperation or synergy among random variables in predicting a single target random variable is an important problem in many complex systems. We review three prior infor…
Passive and Driven Trends in the Evolution of Complexity
Larry Yaeger, Virgil Griffith, Olaf Sporns
The nature and source of evolutionary trends in complexity is difficult to assess from the fossil record, and the driven vs. passive nature of such trends has been debated for deca…
Ideal Free Distribution in Agents with Evolved Neural Architectures
Virgil Griffith, Larry S. Yaeger
We investigate the matching of agents to resources in a computational ecology configured to present heterogeneous resource patches to evolving, neurally controlled agents. We repea…
Quantifying synergistic information remains an unsolved problem
