Exercise

Visualizing transformed radially separable data

In this exercise you will transform the radially separable dataset you created earlier in this chapter and visualize it in the x1^2-x2^2 plane. As a reminder, the separation boundary for the data is the circle x1^2 + x2^2 = 0.64(radius = 0.8 units). The dataset has been loaded for you in the dataframe df.

Instructions

  • Transform data to x1^2-x2^2 plane.
  • Visualize data in terms of transformed coordinates.
  • Add a boundary that is linear in terms of transformed coordinates.
