Answer ( 1 )

  1. 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.For example linear, nonlinear, polynomial, radial basis function (RBF), and sigmoid.

    Polynomial kernel- It is popular in image processing

    Gaussian kernel -It is general purpose kernel. used when there is no prior knowledge of data

    Sigmoid kernel -we can use it as a proxy for neural network
