Default Re: I think Q9 average number of irritations is related to implementation of PLA?!

Ah... I see my mistake now. I generated data x1,...,xn (uniformly on [-1,1]^2) and I fixed it forever. Then, I applied the PLA 1000 times to learn from the fixed data. (In every run, at each iteration, the PLA chooses the misclassified point randomly). In this way I obtain figure 1. Next, I generated new data x1',...,xn', fixed it, and applied the PLA 1000 times again. This resulted into figure 2.

Instead of fixing the sample, I should have generated new data for each PLA run!

Thank you! Looking forward to solving HW2
