  • Iteration with Optics

    In this post I'll describe the theory of how to add iteration to categories of optics. Iteration is required for almost all applications of categorical cybernetics beyond game theory, and is something we've been handling only semi-formally for some time. The only tool we need is already one we have inside the categorical cybernetics framework: parametrisation weighted by a lax monoidal functor. I'll end with a conjecture that this is an instance of a general procedure to force states in a symmetric monoidal category.
  • Passive Inference is Compositional, Active Inference is Emergent

    This post is a writeup of a talk I gave at the Causal Cognition in Humans and Machines workshop in Oxford, about some work in progress I have with Toby Smithe. To a large extent this is my take on the theoretical work in Toby's PhD thesis, with the emphasis shifted from category theory and neuroscience to numerical computation and AI. In the last section I will outline my proposal for how to build AGI.
  • How to Stay Locally Safe in a Global World

    Suppose your name is x and you have a very important state machine that you cherish with all your heart. Because you love this state machine so much, you don't want it to malfunction and you have a subset which you consider to be safe. If your state machine ever leaves this safe space you are in big trouble so you ask the following question.
  • AI Safety Meets Value Chain Integrity

    Advanced AI making economic decisions in supply chains and markets creates poorly-understood risks, especially by undermining the fundamental concept of individuality of agents. We propose to research these risks by building and simulating models.

    This is a short summary of the post. It is meant to explain how to write for our blog.
  • A Software Engine For Game Theoretic Modelling - Part 2

    Some time ago, in a previous blog post, we introduced our software engine for game theoretic modelling. In this post, we expand more on how to apply the engine to use cases relevant for the Ethereum ecosystem. We will consider an analysis of a simplified staking protocol. Our focus will be on compositionality – what this means from the perspective of representing protocols and from the perspective of analyzing protocols.
  • What is Categorical Cybernetics?

    Categorical cybernetics, or CyberCat to its friends, is – no surprise – the application of methods of (applied) category theory to cybernetics. The "category theory" part is clear enough, but the term "cybernetics" is notoriously fluid, and throughout history has meant more or less whatever the writer wanted it to mean. So, let’s lay down some boundaries.
