Artificial Intelligence(AI) refers to the simulation of human intelligence in machines that are designed to think and act like humans. These machines can perform tasks that typically require human intelligence. There are various approaches to achieving AI, including machine learning, where systems can learn from data and make predictions or decisions without being explicitly programmed, and expert systems, which are designed to solve complex problems by reasoning about knowledge encoded in software rules. The ultimate goal of AI research is to create systems that can perform tasks that normally require human intelligence, such as visual perception, speech recognition, decision-making, and language translation.
