Default Re: Clarification of Problem 3.1

The problem describes a geometrical region on the plane, half of which is shaded red and the other half blue. You generate 2000 points in this region randomly. If the point (x_1,x_2) lands in the blue region, it is classified blue(+1) and otherwise red(-1). In this way you generate a training data set of 2000 points.

Does that clarify your confusion?

Could anyone possibly demonstrate this question clearly for me? Thanks very much!
