SVM algorithms use a set of mathematical functions that are defined as the kernel. The function of kernel is to take data as input and transform it into the required form. Different SVM algorithms use different types of kernel functions. These functions can be different types. For example linear, nonlinear, polynomial, radial basis function (RBF), and sigmoid.
Polynomial kernel
It is popular in image processing.
Equation is:
where d is the degree of the polynomial.
Gaussian kernel
It is general-purpose kernel; used when there is no prior knowledge about the data. Equation is:
Gaussian radial basis function (RBF)
It is general-purpose kernel; used when there is no prior knowledge about the data.
Equation is:
, for:
Sometimes parametrized using:
