and we'll just use this from now on in the future to denote dense layers or fully connected layers between two between an input and an output or between an input and hidden layer and again if we wanted to implement this intensive flow the idea is pretty simple we can just define two of these dense layers the first one our hidden layer with n outputs and the second one our output layer with two outputs we can cut week and like join them together aggregate them together into this wrapper which is called a TF sequential model and sequential models are just
