The Underlying Assumption
- The Physical Symbol System Hypothesis
- Symbols as part of expressions
- System containing symbol structures
- Expressions producing other expressions
- A physical symbol system produces, through time, an evolving collection of SS
- PSS has necessary and sufficient means for general intelligent action
- Only empirical way to prove (or Disprove!)
Using Computer For It
- Lady Lovelace and ‘Using computers for other things then number crunching’
- Computers to test the PSS hypothesis
- Sophistication in programming to solve more complex problems
- Sub-symbolic systems like visual perception provide evidences in favor
- Psychologists to test the theory of intelligence and building programs that behave live humans
The AI Technique
Intelligence requires knowledge
- Voluminous
- Hard to characterize accurately
- Constantly changing
- To be organized in a way to be used
AI Methods should exploit knowledge
- Generalization
- Input comes as ‘human understandable form’
- Modifiable with meta-knowledge
- Usable even when incomplete or not totally accurate
