Here, the 'sample' refers to the training set, the original set of random points (x1,x2) which are used to solve for the the weights.
The 'outofsample' points are a new set of random points (x1,x2). This set is used to test how well your weights worked on random points
outside the training set, i.e points that were
not used to derive them.
