well shouldn't I just think about it end to end so often in deep learning you have kind of two paths one path is you're gonna try to design something and the other pattern you say hey I'm just think about the result that one is the result that one let me define a loss function on the result I want and then training a staff instead of putting all the modules in more detail together myself so in this case what it might mean well instead of learning representation for a dynamic smaller and then bolt it on a planter or bolting on
