Exercise

SVM with polynomial kernel

In this exercise you will build a SVM with a quadratic kernel (polynomial of degree 2) for the radially separable dataset you created earlier in this chapter. You will then calculate the training and test accuracies and create a plot of the model using the built in plot() function. The training and test datasets are available in the dataframes trainset and testset, and the e1071 library has been preloaded.

Instructions

100 XP
  • Build SVM model on the training data using a polynomial kernel of degree 2.
  • Calculate training and test accuracy for the given training/test partition.
  • Plot the model against the training data.
