Artificial Intelligence (AI) is a rapidly evolving field which involves the application of computer science to enable machines to act intelligently. The major AI technologies can be broadly classified into Machine Learning, Natural Language Processing, Computer Vision and Robotics. Machine Learning is a subset of AI which enables machines to learn from data and make decisions without being explicitly programmed. Natural Language Processing allows machines to understand and manipulate language, while Computer Vision allows machines to process and interpret visual data. Robotics is the branch of AI which focuses on creating autonomous machines that can interact with and manipulate their physical environment. All of these technologies are being used to create intelligent systems that can automate tasks and solve complex problems.
