For the double semicircle task in Problem, vary sep in the range {0.2, 0.4, ... , 5}.
Generate 2, 000 examples and run the PLA starting with w = 0. Record the number of iterations PLA takes to converge. Plot sep versus the number of iterations ta ken for PLA to converge. Explain your observations.
Problem:-
Consider the double semi-circle "toy" learning task below.
There are two semi circles of width the k with inner radius rad, separated by sep as shown (red is -1 and blue is +1). The center of the top semicircle is aligned with the middle of the edge of the bottom semicircle. This task is linearly separable when sep 2: 0, and not so for sep k = 5 and sep = 5. Then, generate 2, 000 examples uniformly, which means you will have a pproximately 1, 000 examples for each class.
(a) Run the PLA starting from w = 0 until it converges. Plot the data and the final hypothesis.
(b) Repeat part (a) using the linear regression (for classification) to obtain w. Explain your observations.
