Introduction to Artificial Intelligence (AI)
Definition of AI
Artificial Intelligence (AI) is a branch of computer science focused on creating
systems capable of performing tasks that typically require human intelligence.
These tasks include reasoning, learning, problem-solving, perception, language
understanding, and decision-making.
Key Definitions:
John McCarthy (1956): "The science and engineering of making intelligent
machines."
Elaine Rich: "AI is the study of how to make computers do things at which,
at the moment, humans are better."
History of AI
Timeline Overview:
1940s-50s (Foundations):
o Alan Turing proposed the concept of a "universal machine" (Turing
Machine).
o 1950: Turing Test introduced in “Computing Machinery and
Intelligence”.
1956 (Birth of AI):
o Dartmouth Conference – John McCarthy, Marvin Minsky, Nathaniel
Rochester, and Claude Shannon formalized AI as a field.
1960s-70s:
o Early AI programs (e.g., ELIZA, SHRDLU).
o Success in problem solving and symbolic reasoning.
1980s:
o Rise of expert systems (e.g., MYCIN).
o AI Winter due to unmet expectations and funding cuts.
1990s-2000s:
o AI integrated into industrial applications.
o Notable milestones: IBM's Deep Blue beats Kasparov (1997).
2010s-present:
o Rapid advances due to big data, deep learning, and computational
power.
o Milestones: Siri, AlphaGo, autonomous vehicles, ChatGPT.
