Artificial intelligence (AI)

Artificial intelligence is the branch of computer science focused on creating systems capable of performing tasks that normally require human intelligence. These tasks include learning, reasoning, problem solving, pattern recognition, natural language processing, and decision-making. AI systems can be narrow, designed for specific tasks, or general, intended to perform a broad range of cognitive activities.
AI is now a core driver of innovation in business and technology, powering applications from voice assistants to predictive analytics, automation, and robotics.
Advanced
AI relies on algorithms, statistical models, and large datasets to simulate intelligence. Machine learning, a key subset, allows systems to improve performance over time without explicit programming. Deep learning, which uses multi-layered neural networks, powers image recognition, speech understanding, and generative models.
AI is integrated into enterprise systems, cloud platforms, and edge devices. More sophisticated deployments use reinforcement learning, explainable AI, and hybrid architectures that combine symbolic reasoning with neural models.
