Given the following 4 vectors in the plane and their labels
x1 = (0,3) y1 =1
x2 = (0, 2) y2 =1
x3 = (1,1) y3 = −1
x4 = (2,1) y4 = −1
find the optimal margin classifier by hand. give me a formula for the decision boundary and a make sketch including the data points, the decision boundary and indicate which data points are the support vectors.
