Question:
Recall that for a standard HMM the Elapse Time update and the Observation update are of the respective forms:
P(Xt | e1:t−1) = Σxt−1 P(Xt | xt−1)P(xt−1 | e1:t−1)
P(Xt | e1:t) ∝ P(Xt | e1:t−1)P(et | xt)
We now consider the following two HMM-like models:
Derive the modified Elapse Time update and the modified Observation update that correctly compute the beliefs from the quantities that are available in the Bayes’ Net.
