For example, the retinal image of a chair is insufficient to represent the universal concept of a chair. The retinal image must be recognized as a typical chair pattern and must be associated with a verbal label by some sort of digital mechanism.
Zenon Pylyshyn (1974).
Note: Pylyshyn allows that some analogue computations may be important in practice, and he thinks it is likely that practical AI systems will use hybrid analogue-digital mechanisms. He is arguing against the claim that all mental computation is analogue. |
