neural network in the neural network comes up with a number of how well those three things fit together and then you can transfer these concepts that's pretty cool now the only question is of course and we've always said we're given an energy function or just we just have it but of course this is a neural network and the neural network has parameters and the parameters we don't know what good parameters are at the beginning so we need to train this thing and again the reason why these are toy problems right here is I mean we'll get
