Drawing boundary line for PLA
Hello,
This is not exactly related to HW(which I have submitted). I want to visually observe how boundary line changes after each iteration i.e I want to know how to draw a boundary line after each iteration of PLA. Initial or actual boundary line (rep target function) is known to me since it is selected as two random points and I can draw the line. One iteration gives me a new weight vector , so how do I relate this to boundary line. Thanks and I apologize for any wrong use terminologies.

Re: Drawing boundary line for PLA
Since we use the sign function, I presume the decision boundary is
g(x) = w'x = 0 (including the bias w_0) One strategy could be to generate values on the grid [1,1] x [1,1], and plot where g evaluates to 0. But that is costly for each iteration. Hopefully there is a better approach.
