What is artificial intelligence? ​

No universally accepted definition. AI is the endeavor of building intelligent artifact.

• ability to learn
• faculty of good sense, to adapt to circumstances
• ability to perform well in an intellingence test
• branch of computer science dealing with the simulation of intelligent behavior in computers
• program that can sense, reason, act and adapt
• pass the turing test (the imitation game)

Mimicking human behavior

Weak AI: can a machine exhibit intelligent behavior? Strong AI: can a machine be self-aware?

Artificial Intelligence vs Machine Learning vs Deep Learning (AI vs ML vs DL) ​

AI: A program that can sense, reason, act and adapt ML: Algorithms whose performance improve with experience as they are exposed to more data over time DL: Subset of ML in which multi-layered neural networks learn from vast amounts of data
