When dealing with complex and redundant data classification problems, many classifiers cannot provide high predictive accuracy and interpretability. We also find that the least-squares support vector classifiers (LSSVCs) hardly identify important instances and features from data, so they cannot give an interpretable prediction. Although the LSSVC h...
Fuzzy association rule mining (FARM) is a mainstream method to discover hidden patterns and association rules in quantitative data.
