Artificial intelligence (AI) is a field of computer science that focuses on creating systems and machines that can perform tasks that would normally require human intelligence. This includes things like learning, reasoning, problem-solving, perception, and understanding human language. AI systems learn from data rather than being explicitly programmed with every possible scenario. This allows them to identify patterns, make predictions, and improve their performance over time. The core principle of AI revolves around training these systems on vast amounts of data, which helps them recognize relationships and trends that humans might miss.
