A classifier is an AI that sorts things into buckets. Cat or dog. Spam or not spam. Fruit or veggie. Today you train one yourself, using examples. The AI learns from whatever you show it, so the better your examples, the smarter it gets.
Pick your two categories (for example, fruit vs. vegetable)
Give it clear examples of each
Test it on new items it has never seen
Add more examples where it gets confused
Where classifiers show up in real life
Your email inbox (spam vs. not spam)
YouTube's 'you might like' picks
Hospital scans that flag possible cancer
Self-driving cars deciding what a blob in the road is
The big idea: classifiers are one of AI's most-used superpowers. They are everywhere, quietly sorting your digital life. Now you know how they get trained.
