AI: How It Actually Works

Cut through the hype and learn what AI, machine learning, and deep learning really are.

Prerequisite: Data & Applications

What you'll actually learn

"AI" gets used for three genuinely different things stacked on top of each other, and most confusion comes from never separating them: machine learning (a program that improves at a task from data instead of explicit rules), deep learning (a specific family of ML built on layered neural networks), and the modern AI systems built on top of both. This track draws those boundaries clearly and grounds each one in a concrete example instead of a marketing definition.

What you'll be able to do

You'll be able to look at a real product's "AI-powered" claim and actually evaluate it — is this a hand-tuned rule, a trained model, or something in between — instead of taking the label at face value, and explain the difference to someone else without reaching for jargon you don't actually understand yourself.
