Jules Hedges | Compositional Game Theory - Towards Incentives Modelling at Scale
Jules is a mathematician and computer scientist who was a pioneer of the recently developed field of applied category theory. His main scientific interests are in microeconomics and machine learning. He is a co-founder of the Institute for Categorical Cybernetics (cybercat.insti...), a nonprofit organization for research and open source software development, and 20squares (20squares.xyz/), a startup specializing in applied mechanism design and economic modelling in the blockchain space. By day he is a lecturer in computer science at the University of Strathclyde in Glasgow, Scotland.

Compositional game theory is an approach to modelling interactions of strategic agents which is designed to be inherently scalable, in contrast to traditional normal-form and extensive-form games that are unsuitable for anything larger than toy problems. It supports a model-is-code paradigm and reuse of model components, inspired by software engineering. I won’t have time to talk much about how compositional game theory works, so instead this will be a taster of what it looks like and what it can do: we have used it in settings such as applied mechanism design, smart contract analysis and the theory of institution design. At the end I’ll hint at a much bigger picture: the mathematical foundations of compositional game theory also appear in several different parts of machine learning and other fields, something we call “categorical cybernetics”, and I’ll discuss what the implications of this could be.

About The Foresight Institute
The Foresight Institute is a research organization and non-profit that supports the beneficial development of high-impact technologies. Since our founding in 1986 on a vision of guiding powerful technologies, we have continued to evolve into a many-armed organization that focuses on several fields of science and technology that are too ambitious for legacy institutions to support. From molecular nanotechnology, to brain-computer interfaces, space exploration, cryptocommerce, and AI, Foresight gathers leading minds to advance research and accelerate progress toward flourishing futures.
We are entirely funded by your donations. If you enjoy what we do please consider donating through our donation page: foresight.org/...

Folder of time

[@JeremyHelm]

3:56 the structure of bodies seems critical for communication? Vision Pro may have the best eye tracking, but your mouse gets chopped off in zoom?

[@JeremyHelm]

4:32 as a listener, I'll have to actively create for myself the bouncy ball of singing along with the meaning of words projected into some kind of visualization

[@JeremyHelm]

6:56 strategy "how to transform from what you can see, to what you can do" stating this perfectly as to be compatible with mimesis?

[@JeremyHelm]

7:47 so, time just doesn't end, then?

[@JeremyHelm]

8:12 so we're acting as if the rules of the game are consistent? Known?
