propagate kind of directions so the activations are sort of impulses whereas the backward signals are this isn't how you need to change their their gradients ultimately so it's fundamentally a different type of data that is propagated along would be propagated along these directions and that makes it very unlikely because we are not aware as this paper says that the that neural networks that neurons can kind of switch the data type that they're they're transmitting all right so then the paper goes into their end
