Good AI governance should enable responsible adoption, not simply restrict it.

My latest article for @TheAIJournal1 explores why practical guardrails, AI literacy & accountability matter as AI becomes embedded in everyday work.

One of my favourite things about teaching AI is showing that the math isn't there to make ML harder, it's what makes it understandable.

Check out my ML Math presentation for @Cohere_Labs ML Summer School - covering calculus & linear algbebra:

Modern ML optimizers aren’t just update rules, they’re sophisticated ways of navigating complex loss geometry. My latest video with @Cohere_Labs breaks down the evolution from SGD to OLion through the lens of Taylor approximations.

Taylor Series aren’t just a calculus topic, they’re foundational to ML optimization. My latest video with @Cohere_Labs breaks down how local approximations of loss functions lead to Gradient Descent and Newton’s Method.

🔢 @KatrinaL2899 has been leading the ML Math Group for two years and brings so much enthusiasm to everything she does. From participating in multiple Expeditions to hosting one of our biggest ML Summer School sessions on math, Katrina’s passion for the field is clear. She’s even launched her own YouTube channel focused on all things math - an extension of the dedication she brings to the community.
