Comprehensive evaluation of twin SVM based classifiers on UCI datasets

In the past decade, twin support vector machine (TWSVM) based classifiers have received considerable attention from the research community. In this paper, we analyze the performance of 8 variants of TWSVM based classifiers along with 179 classifiers evaluated in Fernandez-Delgado et al. (2014) from 17 different families on 90 University of California Irvine (UCI) benchmark datasets from various domains. Results of these classifiers are exhaustively analyzed using various performance criteria. Statistical testing is performed using Friedman Rank (FRank). Our experiments show that two least square TWSVM based classifiers (ILSTSVM_m, and RELS-TSVM_m) are the top two ranked methods among 187 classifiers and they significantly outperform all other classifiers according to Friedman Rank. Overall, this paper bridges the evaluational benchmarking gap between various TWSVM variants and the classifiers from other families.
