Default Re: Doubt on weights and pla

If it is already known that the target function is linear and passes through (0,0) (such as f(x) = x), then it is known that bias term will be zero. [ -1 , 1] makes sense, which is indeed equivalnet to [-n,n]. However, if it's not the case, you do need the bias term (weight vector will have length of 3), otherwise the algorithm may not converge.
