Artificial intelligence overview and applications

Definition of artificial intelligence

Artificial intelligence (AI) is a computer program or machine that can learn and mimic human thinking. It is also described as a system’s ability to understand external data, learn from it, and use what it has learned to achieve specific goals or tasks through adaptation. The term AI is sometimes used to refer specifically to neural networks or deep learning. AI is often framed as enabling intelligent behavior—such as perceiving information from the environment, reacting to it, and improving chances of success. The content also distinguishes between strong AI (aiming to build machines that can think like people) and weak AI (building systems that support humans). In practice, AI is used across many areas, including speech and image recognition, robotics, natural language processing, translation, predictive analytics, medical diagnostics, fraud detection, and control of physical processes.
