Complementary learning fuzzy neural network

Abstract

Computational intelligence (CI) is gaining more attention as its applications in various areas grow. Soft computing is one of the popular CI facets because of its ability to handle imprecision and uncertainty. Artificial Neural Network (ANN), neuro-juzzy system,juzzy expert system, and statistical method are the prominent tools within this discipline. However, these systems infer mainly from the class of interest (positive class). The information about the differences among classes are not fully utilized. Some systems, on the other hand, do not consider the class information at all. Although these systems perform well, their performance could be further enhanced if the contribution from' negative class is taken into account. Moreover, constructing knowledge based on single class alone may cause the system to under-perform when the data is imbalanced. Viewing from the other end, most of these systems focus on boosting the accuracy, but disregard the psychological needs of user. They lack the reasoning, inference, and validation processes that user can identify with. CI system based on ANN or statistical method provides no means of understanding the system, while some expert system requires manual construction of knowledge. Furthermore, most of them are independent of biological or psychological principle, which hinder the user acceptance and trust towards the system. The debut of high-dimensional and ultra-huge databases exacerbates the situation.
