Clustering is to find a solution to categorize the input data into some groups. The process of clustering is dialectical: Firstly, the training data is known (visible) but the solution is unknown (invisible). Secondly, the training data x decides the solution y in training but y decides x in running. This interesting phenomenon fits well with the famous Chinese ancient Ying-Yang philosophy: First, everything in the universe can be viewed as a product of a constant conflict between opposites – Ying and Yang, with Ying referring to negative, female and invisible, whereas Yang referring to positive, male and visible. Second, the optimal status is reached if Ying and Yang achieves harmony. This research attempts to construct a novel fuzzy neural network, in which Bayesian Ying-Yang (BYY) learning is introduced to determine the optimal fuzzy sets. The experimental results on some benchmark datasets show that the proposed model outperforms the existing representative techniques. The proposed model has been successfully applied to fingerprint recognition, and will be applied to robot navigation in our future work.
