coding and then we'll switch to a very different kind of coding scheme okay now I'll switch to think about how I can use a variational auto encoder something called bits back coding and a symmetric numeral systems to encode information this at least to me is one of the most was one of the most mind-boggling thinks how does this even possible they're confusing at first but I hope that you know - the way we laid it out in the slice at all again be clear how does exactly works but there's this notion somehow you get bits back and hence you
