I love this video, it's much better than the mechanical approach to Variable Elimination. Now I understand WHY it works, and it is so much easier to remember!

From 14:00 How was sum over E written as f1(A,B) and sum over B written as f2(A)?

I don't understand how that full joint distribution summing over hidden variable came. EE Dept.

@Akash We have assumed that Earthquake and Burglary are two independent events and they influence Alarm. Hence P(B) and P(E) are multiplied as they are. But alarm ringing depends on E and B hence P(A|,E.B). Since alarm influences John calling or Mary calling, we have P(j|A) and P(m|A). Hence P(B) P(E) P(A|E,B) P(m|A) P(j|A)

@@kpb6 I have one more doubt , what if we have some more parents to earthquake and burglary and some more child nodes to john and mary ?? Do all these things should be considered as hidden variables for computations?

@@manjunathakapilsharma Precisely. For instance: if [Earthquake] had 2 causal nodes (i.e. parents), then we would do P(E | parents) etc.

If u can mention the particular timestamp, we might be able to exactly clarify the doubt.

Good lecture, but he expects students to guess what he's about to say often without it yet being clear what he's looking for, which seems common in teaching probability.
