"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.
