while you would do is you would put a lot of weight on this this this and this ball and no weight on that ball because those make a line and since everything here is differentiable so the state is differentiable the attentions differentiable and the concepts or vectors that are differentiable you can use gradient descent to find that another example if you're given again the same W so line and you were given this following thing and you were given now you're given the attention on these three and you say please find the X
