Final answer:
Artificial intelligence (AI) refers to computer systems that perform tasks requiring human intelligence. It is used in various fields and implemented using machine learning and deep learning.
Step-by-step explanation:
Artificial intelligence (AI) refers to the development of computer systems capable of performing tasks that typically require human intelligence, such as visual perception, speech recognition, decision-making, and problem-solving.
AI algorithms can be used in various fields, including finance, healthcare, self-driving cars, and facial recognition software. Examples of AI applications include virtual assistants like Siri and Alexa, recommendation systems like those used by Amazon and Netflix, and autonomous drones.
AI is often implemented using machine learning, which involves training the computer system with large amounts of data to enable it to recognize patterns and make predictions or decisions. Deep learning, a subset of machine learning, uses artificial neural networks to simulate the human brain's architecture and process information.
