Classic SVM kernel functions.

Kernel	Form	Advantage	Disadvantage
Linear		High efficiency	Unable to deal with a nonlinear task
Polynomial		Solving nonlinearity	Too excess parameters
Radial basis		Single parameter, mapping infinite dimension, training is extremely robust and efficient [16]	Calculate too slowly and risk of overfitting
Sigmoid		Multilayer perceptron neural network	Poor effect, rarely used

are kernel parameters.
