Machine Learning

USUK

A subset of AI where systems learn from data to improve performance without explicit programming.

Also: ML

Definition

Machine learning is a branch of artificial intelligence in which algorithms and statistical models enable computer systems to learn from data and improve their performance on tasks without being explicitly programmed with rules. It encompasses supervised learning, unsupervised learning, and reinforcement learning. Applications include image recognition, natural language processing, recommendation systems, and fraud detection.

Example

A spam email filter uses machine learning: it is trained on millions of labeled emails (spam and not spam), learning patterns in words, sender addresses, and formatting, then applies this knowledge to classify new incoming emails accurately.
