Overview
Artificial intelligence brings together ideas from computer science, statistics, cognitive science, and many application domains. It is less a single technique than a family of approaches for turning observations, objectives, and constraints into useful decisions or generated outputs.
What it is
AI studies computational systems that perform tasks associated with intelligent behavior, including perception, planning, language use, prediction, and decision-making. Some systems rely on explicit rules; others learn representations and policies from data.
How it works
An AI system usually combines a task definition, data or observations, a model, and an evaluation procedure. During training or design, the system is adjusted against an objective. During use, it processes new inputs and produces predictions, actions, rankings, or content, often with safeguards and human oversight.
