I am often asked to suggest learning material for working professionals who are interested in (re)training themselves to work in or with AI. The following document, which I put together a little while ago, recommends a series of short foundational courses suitable for people pursuing self-paced learning on different aspects of AI. Section 6 is … More AI Short Courses for Self-Paced Learning
In the last 10 years or so, there has been a paradigm shift in how we train AI models. In particular, the best practice has shifted from Model-Centric AI, where we endless tweak model architectures and algorithms in pursuit of better performance, to what we now call Data-Centric AI, where we keep the model architecture … More Integrating Data for AI : All You Ever Wanted To Know About Metadata Standards, Ontologies, Data Models, and Process Models But are Too Afraid to Ask
In a recent TED talk titled One Thing to Teach in the Age of AI, innovation practitioner Bryan Cassady shared a story about an exam created by one of his colleagues. The exam question was deceptively simple: “Prove you’ve learned the material in this course by giving me five good questions.” Many students struggled with that, and certainly … More What Makes a Good Question in the Age of AI
If AI really turns out to be normal technology, an increasingly persuasive case Arvind Narayanan and Sayash Kapoor have continued to advance, what happens to the competitive dynamics and industry structures for the organisations operating in that space? Using a synthesis of Porter’s Five Forces Framework, Helmer’s Seven Powers and Oberholzer’s Value Stick that I … More If AI really turns out to be a normal technology, what happens to industry structures?
A significantly expanded version of a paper I shared earlier on Privacy Technologies for Financial Intelligence is now published in the Journal of Economic Criminology’s Special Issue on Economic Crime in a Changing World: Emerging Threats and Strategic Responses. The paper is open-access and written for a broad non-technical audience. It can be found here: … More JEC Special Issue on Economic Crime in a Changing World
We have substantially revised the factored conditional filtering paper to frame it more generally as a solution for belief acquisition in AI agents. Here’s the revised paper on arXiv. https://arxiv.org/abs/2206.02178v3 Here’s the abstract: This paper studies how belief acquisition can be accomplished using stochastic filtering. First, a theoretical foundation for empirical beliefs is outlined. Then … More Belief Acquisition as Stochastic Filtering
Using sequential hypothesis testing techniques to check the modelling assumptions of Bayesian mixture estimators is a promising way of getting value out of combining the Bayesian and frequentist approaches to probability. Here’s a paper to show how that can be done for Context Tree Weighting and related methods. Paper Abstract: Universal Bayesian sequence predictors like … More Martingale Tests for Model Misspecification in Bayesian Sequence Prediction
All my life I have been searching for simple and effective methods for constructing prediction intervals for different AI/ML models. I don’t know why I never encountered Conformal Prediction until recently, but I suppose it is better late than never. Conformal prediction is (arguably) the most elegant and practical technique for improving the robustness in … More Notes on Conformal Prediction and Testing
Threat modelling is now considered a best practice in comprehensive technical approaches to dealing with AI safety issues [S+25]. Threat modeling [S14] is a structured, proactive process used to identify potential threats and vulnerabilities in a system. While the traditional focus is on cyber-security and privacy issues, threat modelling has been extended for AI systems … More AI Risk Assessment via Threat Modelling
AI governance and AI assurance are sometimes conflated in conversations but they are not the same thing. In simple terms, An AI Governance Framework sets the Rules and Structure (the What and Who) and establishes the overall system for decision-making and accountability. An AI Assurance Framework is there to demonstrate Compliance and Trust (the How); … More AI Governance vs AI Assurance
