Thank you shooltz
Re: DBN, inference algorithms and unrolling
Hi
I have unrolled my DBN to 5 time slices. I have entered evidences for the 5 time slices and performed the inference using the Polytree algorithm. Is the inference considered Filtering in this case P(Xt|y1:t)?
Regards

Re: DBN, inference algorithms and unrolling
Depends on your model structure, but assuming you set evidence for "evidence nodes" and are looking at the "hidden nodes", I'd say yes if you are looking a the hidden node x in time slice 5.
