2016 PLoS ONE  
Conclusions This work summarizes SVM classifiers obtained with linear, polynomial and RBF kernels in a single plot. Linear and polynomial kernels up to the second degree are represented exactly.  ...  For other kernels an indication of the reliability of the approximation is presented.  ...  The two SVM models with optimal tuning parameters are: a first SVM model with an RBF kernel (γ = 2 −4 and C = 10 5 ) and a second SVM model with a polynomial kernel (δ = 4 and C = 100).  ...
