How others define AI1. "a collection of algorithms that are
computationally tractable, adequate approximations of intractably specified problems" (Partridge, 1991)
2. "the enterprise of constructing a physical symbol system that can reliably pass the Turing Test" (Ginsberg, 1993)
3. "the field of computer science that studies how machines can be made to act intelligently" (Jackson, 1986)

How others define AI4. "a field of study that encompasses
computational techniques for performing tasks that apparently require intelligence when performed by humans" (Tanimoto, 1990)
5. "a very general investigation of the nature of intelligence and the principles and mechanisms required for understanding or replicating it" (Sharples et al., 1989)
6. "the getting of computers to do things that seem to be intelligent" (Rowe, 1988)

Defining AI
For most people, a definition of AI centers around the concept of "intelligence" and some form of the questions: What is intelligence? How can minds work? How do human minds work? Can non-humans have minds?

Defining AI
These questions weren’t invented by computer scientists. They have puzzled philosophers, biologists
and psychologists for centuries.

How this course will define AI
Artificial Intelligence is a science that has defined its goal as giving machines the ability to perform tasks that, when performed by humans, require intelligence. These include the ability to solve problems, make decisions, to learn and to understand.
