Artificial Intelligence (AI) refers to the simulation of human intelligence in machines that are programmed to think, learn, and perform tasks that typically require human intelligence. AI involves the development of computer algorithms that can analyze and interpret complex data, recognize patterns, make predictions, and solve problems.

AI systems are designed to perform a range of tasks, from simple ones such as identifying images to more complex ones such as natural language processing, speech recognition, and decision-making. These systems can be trained using large datasets and sophisticated algorithms to improve their accuracy and performance over time.

AI is used in a variety of applications, including robotics, autonomous vehicles, healthcare, finance, and customer service. AI is also used in various forms of machine learning, such as deep learning and neural networks, which allow machines to learn and improve without being explicitly programmed.
