because and it's basically the standard basis right and any other task can be mixed from those so these are orthogonal vectors in this vector space so you're being pretty generous to this system what happens if we're not as generous so that's what they do here so they have different um policies and they evaluate how much you can learn with these different policies so the way you have to read this diagram is right here is going to be the one zero axis as they well they label it right here and this is going to be the zero one axis and
