Artificial intelligence refers to systems that perform tasks normally requiring human intelligence, such as recognizing speech or solving problems. This foundational field blends computer science, mathematics, and data to create models capable of learning from experience rather than relying on explicit programming.
A Brief History of AI
- 1950s: Alan Turing asks “Can machines think?” and defines the Turing Test.
- 1960s–80s: Expert systems tackle narrow problems like medical diagnoses.
- 1997: Deep Blue defeats Garry Kasparov in chess.
- 2012–Present: Deep learning breakthroughs such as AlexNet and transformers spark a renaissance in vision and language.
Core AI Technologies
