Alternatives to the Representation Hypothesis
Not everyone accepts the representation
hypothesis. Some alternatives include:
- Analog information, as in homeostatic control (e.g., regulation
of body temperature).
- Special-purpose hardware, such as line
detectors in early vision processing.
- Neural networks with weights on the
connections between neurons. It may be
difficult or impossible to identify ``symbols'' in
such a network; the knowledge is represented
by the totality of the set of weights.
- Holograms and various mystical alternatives.
Critics include Brooks,[Brooks, Rodney A., ``Intelligence without
representation'', Artificial Intelligence 47 (1991), 139-159.]
