Question 3. [20 points] A support vector classifier was fit to a small data set with 12 instances. The colors indicate their classes (Blue represents positive and red represents negative). The hyperplane (solid line) and the two margins (dashed lines) are plotted in the following figure.

(b) Suppose instance 4 (the red dot in the figure) moves closer to the margin. Will it affect the hyperplane? (c) List the number of instances that move across its margin while not the hyperplane. (d) List the number of instances that move across the hyperplane
