Artificial Intelligence (AI) is a field of computer science that focuses on creating systems capable of performing tasks that typically require human intelligence. These tasks range from simple ones, like recognizing speech and images, to complex ones such as reasoning, decision-making, and learning. AI encompasses a wide range of techniques, including algorithms and models that enable machines to solve problems, adapt to new information, and even learn from past experiences. The idea behind AI is to emulate cognitive functions such as perception, reasoning, and problem-solving to build systems that can act autonomously in complex environments.
