I couldn't understand @1:12:31 when the professor said: "I can never represent a joint distribution in which the variables are not independent.". Does it mean that in a joint distribution, the variables must be independent? Or the professor said this under some certain context? Thanks.

He meant "I can never [using a Bayes Net with no arcs] represent a joint distribution in which the variables are not independent".

for the traffic example at 28:22 . maybe robot holds an Umbrella means it's been raining long time before robot goes out, and this might means more traffic and changes our probability, because know P(T | R, U) != P(T | R) != P(T | U) so it's no more conditionally independent (10mins raining varies to 1 hour raining in a traffic model)

I was confused at kzfaq.info/get/bejne/fLuegseqv8ClkXk.html, because I thought independence imply conditional independence at 24:40. Turns out independence doesn't imply conditional independence
