Artificial Intelligence (AI) refers to the simulation of human intelligence in machines that are programmed to mimic human-like tasks such as learning, reasoning, problem-solving, perception, and decision-making. AI systems can analyze large amounts of data, recognize patterns, and adapt their behavior accordingly, often surpassing human capabilities in speed and accuracy. There are various subfields within AI, including machine learning, natural language processing, computer vision, robotics, and more. AI has widespread applications across industries, from healthcare and finance to transportation and entertainment, and is increasingly shaping our daily lives through technologies like virtual assistants, recommendation systems, autonomous vehicles, and smart devices. Ultimately, the goal of AI is to create intelligent systems that can perform tasks autonomously, learn from experience, and continuously improve over time.
