About VRIFA:
VRIFA, written in C#.NET, is a nonlinear SVM visualization tool using nomogram and localized radial basis function (LRBF) kernels. It is implemented based on the paper, " Nonlinear Support Vector Machine Visualization for Risk Factor Analysis using Nomograms and Localized Radial Basis Function Kernels" by Baek Hwan Cho, et. al, and " .NET conversion of LIBSVM" by Matthew Johnson. It currently supports linear and LRBF kernels.
