A Principled Infotheoretic Ï-like Measure
arXiv:1401.0978
Abstract
Integrated information theory is a mathematical, quantifiable theory of conscious experience. The linchpin of this theory, the $Ï$ measure, quantifies a system's irreducibility to disjoint parts. Purely as a measure of irreducibility, we pinpoint three concerns about $Ï$ and propose a revised measure, $Ï$, which addresses them. Our measure $Ï$ is rigorously grounded in Partial Information Decomposition and is faster to compute than $Ï$.
