Abstract:
---------
This talk describes RULEIN/RULEX, an automoated technique for the
refinement of a knowledge base. RULEIN constructs a Rapid Backprop (RBP)
artificial neural network from an initial, partially complete/accurate
knowledge base which is given as a set of propositionla rules. The RBP
network is trained on a set of examples drawn from the problem domain.
RULEX is then used to extract a set of 'refined' propositional rules from
the weights of the trained network. The refined rules represent the
original knowledge base modified in the light of network training. Results
demonstrate that the use of prior knowledge in this manner can decrease
network training time and bias the learning away from local minima. The
method has many applications but is particularly well suited to overcoming
the so called 'knowledge acquisition bottleneck' in the knowledge
engineering phase of rule based expert system construction.
