it into a probability mass function for capital P of Z which is Z times Delta Z so what you get by integrating a density over this small region of volume Delta Z and so you can do that for both the posterior in the prior so you do that for the prior and you do it for the posterior and you see that these deltas use cancel out and so so we get is that this bits back code length with the discretization being the same between the prior and the posterior still gives you the same KL divergence term in the BAE the second point was that that somebody
