Hybrid System for a Never-Ending Unsupervised Learning

We propose a Hybrid System for dynamic environments, where a “Multiple Neural Networks” system works with Bayes Rule. One or more neural nets may no longer be able to properly operate, due to partial changes in some of the characteristics of the individuals. We assume that each expert network has a reliability factor that can be dynamically re-evaluated on the ground of the global recognition operated by the overall group. Since the net's degree of reliability is defined as the probability that the net is giving the desired output, in case of conflicts between the outputs of the various nets the re-evaluation of their degrees of reliability can be simply performed on the basis of the Bayes Rule. The new vector of reliability will be used for making the final choice, by applying two algorithms, the “Inclusion based” and the “Weighted” one over all the maximally consistent subsets of the global outcome.
