set and update VS set all evidence and update once

[sez]

Just want know if there is any difference between way 1 and way 2

way 1 (set and update)
set note evidence -> update
set next note evidence -> update
. . .

way 2 (set all of evidence then update once)
set note evidence
set next note evidence
. . .

update

please advise

Hi

In the end, it doesn't make a difference unless you are interested in the intermediate probabilities after setting evidence one by one.
With either method 1 or 2 , if you check the posteriors of the variables after setting all evidence the result is the same.

Best,

In any case, you'll get better performance with your method 2. In an extreme case, with very large network, method 1 may not complete (SMILE will be able to perform inference with all evidence, while the subset may prove intractable).
