learning and apply the tensor flow implementations to it inside the call function it's the same idea again you can compute Z which is the state it's that multiplication of your inputs with the weights you add the bias right so that's right there and once you have Z you just pass it through your sigmoid and that's your output for that now tension flow is great because it's already implemented a lot of these layers for us so we don't have to do what I just showed you from scratch in fact to implement a layer like this with two two outputs or a percept a multi
