Map of Kernel Models
possible kernels:
polynomial, Gaussian,..., your design (with Mercer’s condition),
coupled with

powerful extension of linear models
with great power comes great responsibility
Map of Linear/Kernel Models

second row: popular in LIBLINEAR
fourth row: popular in LIBSVM
first row: less used due to worse performance
third row: less used due to dense beta
