Information Geometry (Part 15)

It’s been a long time since you’ve seen an installment of the information geometry series on this blog! Before I took a long break, I was explaining relative entropy and how it changes in evolutionary games. Much of what I said is summarized and carried further here:

• John Baez and Blake Pollard, Relative entropy in biological systems. (Blog article here.)

But now Blake Pollard has a new paper, and I want to talk about that:
