...There are only two remaining sets of parameters to tune over the four databases: the first is the sampling radii Rin and Rex of DCP, and the other is the cost parameter c of the linear SVM [39]....

...Moreover, with either linear SVM or score averaging, MDMLDCPs is able to achieve better performance than existing methods, and using both fusion methods the standard error of classification accuracy is consistently smaller than the other approaches....

...For face matching, multi-class classifiers have been used for face identification, such as the nearest neighbor (NN) classifier and the sparse representation classifier (SRC) [4], with two-class classifiers, such as support vector machine (SVM) and Bayesian analysis, being used for verification....

...We observe that: 1) The MDML-DCPs approach achieves superior performance on both Experiment 1 and 4 with the single descriptor DCP. Score fusion by linear SVM also works slightly better than score averaging....

...Both the PLDA classifier and the more recently proposed Joint Bayesian (JB) classifier [35] are tested for face matching, and both linear SVM and score averaging are tested for the score fusion....
