Problem 3.1 Consider the double semi-circle "toy" learning task below. rad sep There are two semi circles of width thk with inner radius rad, separated by sep as shown (red is -1 and blue is +1). The center of the top semi circle is aligned with the middle of the edge of the bottom semi circle. This task is linearly separable when sep > 0, and not so for sep 0, and not so for sep
