two are compatible if Y is a good prediction for X then the energy produced by this is Rho if they are not compatible it's high okay and the way you do inference is that I give you an X you find a why that might be multiple that produces a low energy okay so for example here this is x and y if I give you this X there are two possible answers for why I have low energy right this is the manifold of data that's why they does that our sample form and you know you'll you'll have to answer so I'm not telling you how to do this
