These classes are clearly not linearly separable. Below is a nonlinear SVM contour plot that successfully classified the IRIS dataset using RBF core.
The above figure shows the classification of the three classes of the IRIS dataset.
- From sklearn, we imported the SVM library. li >
- We created 3 non-linear SVM`s (RBF kernel based).
- Each SVM was fed with 1 class kept positive and other 2 as negative. Say, SVM1 had labels corresponding to class 1 only else all were made 0. Same for SVM2 and SVM3 respectively.
- Plot the contour plot of each SVM.
- Plot the data points.
Below is a Python implementation for the same.
