Yeah , so there 's  there 's two separate things , Robert. The f the  the  the Bayes - nets in general are quite good at saying , " if you have no current information about this variable just take the prior for that. " OK ? Th - that 's what they 're real good at. So , if you don't have any information about the discourse , you just use your priors of  of whatever  eh the  discourse  uh , eh , basically whatever w it 's  Probabilistically , whatever it would be. And it 's  it 's sort of not a great estimate ,
Mm - hmm.
but  it 's the best one you have , and , so forth. So that , they 're good at. But the other problem is , how do you fill in all these numbers ? And I think that 's the one he was getting at.
Mm - hmm.
