Default Re: Perceptron Learning Algorithm

Hello Professor,

I have a question regarding updating w on each PLA iteration. If we always assign x0 = 1, how are we reasonably updating w0? By the vector addition, it will always be updated by the value y * x0 = -1 or +1, and if the true w0 is not an integer the PLA will never be able to converge to that value.

Would it be more appropriate to setup such that we divide each component of the true w by w0, so that w0 = 1 always? This way I know it is an integer and my PLA does not have to wander for a non-integer value. Or even, if I know w0 is always 1, I might not even include it in the PLA since I know it is 1 by setup.

Thank you,
-Aaron
