What Is Supervised Learning?

Supervised learning is a type of machine learning in which a model is trained on labeled examples — inputs paired with the correct answers — so it learns to predict the answer for new inputs. Classifying emails as spam or not spam and predicting house prices are typical supervised learning tasks.

Classification vs. Regression

Classification predicts categories (spam or not spam); regression predicts numbers (a price or temperature).

Measuring Accuracy

Models are evaluated on held-out test data, using measures such as the percentage of correct predictions or the average size of errors.
