Core
Artificial Intelligence (AI)
Systems that perform tasks requiring human-like cognition, using techniques like machine learning, natural language processing, and computer vision.
Explained at five levels
Level 1
A computer that can think and learn, kind of like a really smart robot friend.
Level 2
Software that can do things that normally need human brains — like understanding language, recognizing pictures, or making decisions.
Level 3
Systems that perform tasks requiring human-like cognition, using techniques like machine learning, natural language processing, and computer vision.
Level 4
A broad field of computer science focused on building systems capable of performing tasks that typically require human intelligence, including reasoning, learning, perception, and language understanding.
Level 5
A discipline encompassing computational models of cognitive functions — perception, reasoning, learning, and planning — implemented through symbolic, connectionist, or hybrid architectures that approximate rational agency under uncertainty.
