Artificial intelligence (AI) is a broad field of computer science focused on creating intelligent machines capable of performing tasks that typically require human intelligence. These tasks include learning, reasoning, problem-solving, perception, understanding natural language, and even interacting with the environment. AI techniques enable machines to mimic cognitive functions such as learning from data, recognizing patterns, making decisions, and adapting to new situations. AI encompasses various subfields, including machine learning, natural language processing, computer vision, robotics, and expert systems, each contributing to different aspects of intelligent behavior in machines. The ultimate goal of AI is to develop systems that can perform tasks autonomously and efficiently, potentially revolutionizing industries, enhancing productivity, and improving our daily lives.
