Supervised Learning

Fundamentals

Training AI with labeled examples - inputs paired with correct answers - so it learns to predict answers for new inputs.

Supervised learning is teaching by example with an answer key. You feed the model thousands of inputs together with the correct output: emails labeled spam or not spam, X-rays labeled healthy or not, sentences paired with their translations.The model learns the mapping and can then answer for inputs it has never seen. It is the workhorse of practical machine learning - most classification and prediction systems in production, from credit scoring to medical triage, are supervised.
