A new concept learning neural network is presented. This network builds cor
relation learning into a rule learning neural network where the certainty f
actor model of traditional expert systems is taken as the network activatio
n function. The main argument for this approach is that correlation learnin
g can help when the neural network fails to converge to the target concept
due to insufficient or noisy training data. Both theoretical analysis and e
mpirical evaluation are provided to validate the system.
