A Principled Infotheoretic φ-like Measure.
Virgil Griffith · arXiv (Cornell University) · 2014
Integrated information theory [1–3] is a mathematical, quantifiable theory of conscious experience. The linchpin of this theory, the φ measure, quantifies a system’s irreducibility to disjoint parts. Purely as a measure of irreducibility, we pinpoint three concerns about φ and propose a revised measure, ψ, which addresses them. Our measure ψ is rigorously grounded in Partial Information Decomposition and is faster to compute than φ. 1
