🗂️ Job 1 · CLASSIFY
Look at one thing and decide which category it belongs in. Cat or dog? Inbox or spam? Safe or risky?
🔮 Job 2 · PREDICT
Use past patterns to make a smart guess about the future. What comes next? What will you like?
🗂️Classify: Sorting Email into Inbox vs. Spam
A classifier reads the clues (words, sender, ALL CAPS) and drops each email into a category. A high percent means it is very sure.
🔮Predict in Real Life: "You Liked These → Try This Next"
A recommendation system is prediction at work — apps like video, music, and shopping sites use it to guess what you will like next.
🔑Key Terms
🗂️Classification Sorting something into the right group, like inbox vs. spam or cat vs. dog.
🏷️Category One of the labeled groups a classifier can choose from (its possible answers).
🔮Prediction A smart guess about something unknown or in the future, based on past patterns.
⚙️Recommendation System A model that predicts what you might like next from what you (and others) liked before.
🚫Spam Filter A classifier that decides if a message is junk (spam) or something you really want.
📊Confidence How sure the model is, shown as a percent — higher means more certain about its answer.
⭐
Remember: CLASSIFY sorts things into categories now, and PREDICT guesses what comes next — and the model always tells you how confident it is!
