different or better and this this is a big question I answered question there there's no question that the methods that we use the you know current training method our optimization approaches are enabling us to find these free not spline approximations in there truly ridiculously high dimensions right where a lot of these other techniques you wouldn't even attempt to them right but still it does not mean that this is the that we that we've stumbled on the best way of doing this so I think that as we think of new kinds of optimization
