There was a good discussion back in 2020 on BN and PYMC but I haven’t seen anything since.

Bayes Nets, Belief Networks, and PyMC

So I am trying to get my head around how discrete Bayes Nets (sometimes called Belief Networks) relate to the kind of Bayesian Networks used all the time in PyMC3/STAN/etc. Here’s a concrete example: [bayes_net_1] This can be implemented in pomegranate (just one of the relevant Python packages) as: import pomegranate as pg smokeD = pg.DiscreteDistribution({'yes': 0.25, 'no': 0.75}) covidD = pg.DiscreteDistribution({'yes': 0.1, 'no': 0.9}) hospitalD = pg.ConditionalProbabilityTable( [['y…
