Reinforcement Learning in Categorical Cybernetics

no code implementations3 Apr 2024 Jules Hedges, Riu Rodríguez Sakamoto

The outline of the main construction in this paper is: (1) We extend the Bellman operators to parametrised optics that apply to action-value functions and depend on a sample.

The Compositional Structure of Bayesian Inference

no code implementations10 May 2023 Dylan Braithwaite, Jules Hedges, Toby St Clere Smithe

Bayes' rule tells us how to invert a causal process in order to update our beliefs in light of new evidence.

Sheet diagrams for bimonoidal categories

1 code implementation26 Oct 2020 Cole Comfort, Antonin Delpeuch, Jules Hedges

Bimonoidal categories (also known as rig categories) are categories with two monoidal structures, one of which distributes over the other.

Compositional modelling of network games

no code implementations5 Jun 2020 Elena Di Lavore, Jules Hedges, Paweł Sobociński

The analysis of games played on graph-like structures is of increasing importance due to the prevalence of social networks, both virtual and physical, in our daily life.

From open learners to open games

no code implementations22 Feb 2019 Jules Hedges

The categories of open learners (due to Fong, Spivak and Tuy\'eras) and open games (due to the present author, Ghani, Winschel and Zahn) bear a very striking and unexpected similarity.

Proceedings of the 2018 Workshop on Compositional Approaches in Physics, NLP, and Social Sciences

no code implementations6 Nov 2018 Martha Lewis, Bob Coecke, Jules Hedges, Dimitri Kartsaklis, Dan Marsden

Moreover, the interaction between the three disciplines of cognitive science, linguistics and game theory is a fertile ground for research.

Towards Functorial Language-Games

no code implementations20 Jul 2018 Jules Hedges, Martha Lewis

In categorical compositional semantics of natural language one studies functors from a category of grammatical derivations (such as a Lambek pregroup) to a semantic category (such as real vector spaces).

Compositional game theory

1 code implementation15 Mar 2016 Neil Ghani, Jules Hedges, Viktor Winschel, Philipp Zahn

We introduce open games as a compositional foundation of economic game theory.

A Generalised Quantifier Theory of Natural Language in Categorical Compositional Distributional Semantics with Bialgebras

no code implementations4 Feb 2016 Jules Hedges, Mehrnoosh Sadrzadeh

Categorical compositional distributional semantics is a model of natural language; it combines the statistical vector space models of words with the compositional models of grammar.
