Artificial intelligence (AI) is a branch of computer science that focuses on the development of intelligent machines that can perform tasks that typically require human intelligence, such as visual perception, speech recognition, decision-making, and language translation. AI systems use algorithms and data to learn from experience, adapt to new inputs, and perform tasks without explicit programming. AI has applications in a wide range of industries and fields, including healthcare, finance, transportation, and entertainment. Researchers in AI are continually working to improve the capabilities of AI systems, address ethical considerations, and explore the potential benefits and challenges of AI technology.
