Exercise

# Generating a complex dataset - part 2

In this exercise, you will create a decision boundary for the dataset you created in the previous exercise. The boundary consists of two circles of radius 0.8 units with centers at x1 = -0.8, x2 = 0) and (x1 = 0.8, x2 = 0) that just touch each other at the origin. Define a binary classification variable `y`

such that points that lie within either of the circles have `y = -1`

and those that lie outside both circle have `y = 1`

.

The dataset created in the previous exercise is available in the dataframe `df`

.
