Abstract:	摘要： [Display omitted] •A PSO-based rule extractor called a PFHRCNN is proposed to overcome the bottleneck of the knowledge acquisition.•The knowledge embedded in a trained PFHRCNN can be represented by a set of fuzzy If-Then rules.•The performance of the proposed PFHRCNNs is demonstrated on three benchmark medical databases. One of the major bottlenecks in applying conventional neural networks to the medical field is that it is very difficult to interpret, in a physically meaningful way, because the learned knowledge is numerically encoded in the trained synaptic weights. In one of our previous works, we proposed a class of Hyper-Rectangular Composite Neural Networks (HRCNNs) of which synaptic weights can be interpreted as a set of crisp If-Then rules; however, a trained HRCNN may result in some ineffective If-Then rules which can only justify very few positive examples (i.e., poor generalization). This motivated us to propose a PSO-based Fuzzy Hyper-Rectangular Composite Neural Network (PFHRCNN) which applies particle swarm optimization (PSO) to trim the rules generated by a trained HRCNN while the recognition performance will not be degraded or even be improved. The performance of the proposed PFHRCNN is demonstrated on three benchmark medical databases including liver disorders data set, the breast cancer data set and the Parkinson’s disease data set. 其他題名： J Biomed Inform 出版者： United States: Elsevier Inc 出版日期： 2014-06-01 出處： Journal of biomedical informatics, 2014-06, Vol.49, p.53-60 資源來源： Elsevier ScienceDirect Journals Complete 版權： 2014 Elsevier Inc. 版權： Copyright © 2014 Elsevier Inc.
