batch and then do the mixing there and then you can actually backprop through everything everything is differentiable this mixing is differentiable so you can backdrop through any of everything and there's even you know a kind of an engineering trick to only use a single mini batch by mixing it with itself so that's that's pretty neat so this is manifold mix up as you can see here is the that's kind of the description you mix the hidden representations with lambda and you mix the labels with the same lambda and that will become your
