Supervised Learning
A machine learning approach where models learn from labeled examples — input-output pairs provided by humans — to make predictions on new, unseen data.
Supervised learning remains the most widely deployed form of machine learning in production systems. Applications include spam filtering, medical diagnosis, credit scoring, and image classification. The approach requires labeled training data, which can be expensive to create — ImageNet's 14 million labeled images took years to compile. The cost of labeling has driven the growth of data labeling companies, with the market reaching $3 billion annually. Supervised learning achieves its best results when large, high-quality labeled datasets are available.
