The Role of Scale-free and Other Networks in Hierarchical Organization

Nov 08, 2006
Commentary by Stephen Downes

A nice easy read, some good (and knowledgable) discussion of networks, and a couple of interesting observations: first, that "the enormous complexity of the brain depends upon such a balance or interplay between differentiation and integration," Edelman and Tononi (2000) and second, "the basis for the scale-free organization lies in a positive feedback system," which of course OI knew but hadn't quite thought of in exactly that way before (because it implies that scale-free organization can be undermined (as it should be) via negative feedback. I know nothing about the origins of this paper, it being a reference to a Geocities site in an email that was cc'd to me last May (yes, I'm cleaning out my email).
