Episode 20 — Evaluating AI Performance

Knowing that an AI model works is not enough — we need to know how well it works, and under what conditions. This episode explores the frameworks and metrics used to evaluate AI performance. We begin with accuracy, precision, recall, F1 score, and confusion matrices for classification problems, then move to regression metrics like mean squared error and R². For clustering and ranking tasks, we cover silhouette scores, adjusted Rand index, and average precision. Each metric is explained not just technically, but in terms of what it reveals — and what it hides — about system performance.Evaluation goes beyond numbers. Robustness testing with noisy or adversarial data shows whether a model will hold up in real-world conditions. Fairness evaluation ensures systems do not perform unequally across demographics, while explainability testing helps determine if results can be trusted by human decision-makers. We’ll also discuss benchmarks, competitions, and continuous monitoring after deployment. By the end of this episode, listeners will understand that evaluation is a multidimensional process, linking technical performance to fairness, accountability, and reliability.
