Artificial intelligence (AI) is intelligence demonstrated by machines, unlike natural intelligence displayed by humans and animals. AI involves developing intelligent machines that can think and act like humans. There are various types of AI based on the level of intelligence, including narrow AI, general AI, and super AI. AI is being applied across many domains such as healthcare, transportation, marketing, finance, and more. Examples of AI applications include manufacturing robots, self-driving cars, smart assistants, and more. Frameworks for developing AI include TensorFlow, PyTorch, and Keras.
