Artificial Intelligence (AI) refers to the simulation of human intelligence in machines designed to think and learn like humans. It encompasses various technologies and approaches, including machine learning, natural language processing, computer vision, and robotics. AI systems can analyze data, recognize patterns, make decisions, and perform tasks that typically require human intelligence, such as understanding language, recognizing images, and playing games. The goal of AI research is to create systems that can perform complex tasks autonomously, enhancing efficiency and innovation across various industries.
