A Practical Guide to Anomaly Detection
Ever checked your credit card statement and spotted a transaction you didn't make? That's anomaly detection in action — and understanding how it works is more practical than you'd think.
Understanding Anomaly Detection Simply
Imagine you're monitoring your daily heart rate with a smartwatch. Most days, your heart rate stays within a typical range.
But one day, during your usual morning coffee, your watch alerts you that your heart rate is unusually high.
That spike is an anomaly — something that deviates significantly from the expected pattern.
Practical Demo
I built a hands-on demonstration of anomaly detection that covers the core concepts, real-world applications, and common techniques.
You can run the examples directly in your browser — no installations required.
