Exercise 1: Lets first study the simple problem in which only 2 classes (R: Right, E: else) are observed. The balance shows up either C1 (R), when RW + RD > 3 or C2 (E) otherwise. The problem now has only two input features RW and RD. 1- Write a function to create the new data set. 2- Write a function to plot the patterns relatives to classes R and E in different colors and different shapes. Is the problem linearly separable? Give an explanation. Remark: you can include the figure and your response into a markdown cell or provide them in a separate pdf file.
