well um so the authors of this paper implemented this it's back ans algorithm for ve strain on em mist and they found that the numbers that we got were very close are pretty much the same as this as the variational is negative variational the variational bound on the negative block likelihood which is exactly what you want that's what is predicted so this thing works as well as as as advertised you right so in our work what we did was we looked at weight in variable models which are not just one layer so we know
