"Connectionist Expert Systems in a Noisy World"
by Stephen I. Gallant
This talk will describe a model for connectionist expert systems
(MACIE) and show how it is well suited to noisy and redundant
environments.
Connectionist expert systems are diagnostic expert systems
based upon a connectionist model with several interesting features:
-- They can be generated from training examples (and/or rules)
-- They perform forward chaining to make conclusions and
backward chaining to elicit additional information
-- They give IF-THEN rules to justify their inferences, even
though their knowledge base contains no such rules
-- They are arguably less prone to brittle behavior than
traditional expert systems.
In the talk it will be shown how an expert system for a noisy
and redundant problem can be constructed from: (1) a noise-free
model of an underlying process (perhaps a traditional expert
system) and (2) a model for the noise involved. System generation
is entirely automated.
