Question: 3. HMMs (SEng 474, CSc 578D: 10 points) Here is an HMM diagram, adapted from Speech and Language Processing (Jurafsky & Martin, 3rd ed. draft).

3. HMMs (SEng 474, CSc 578D: 10 points) Here is an HMM diagram, adapted from Speech and Language Processing (Jurafsky & Martin, 3rd ed. draft). The temperature of day (hidden state HOT or COLD) changes the number of ice cream cones Dan Jurafsky eats (1,2, or 3). Since the day's temperature impacts the number of ice creams eaten, we can infer the hidden states from just the observed ice cream consumptiorn 0.3 start end 0.5 0.6 0.4 .1 0.7 HOT1 COLD 0.3 2 P(1 | HOT) | | .2 P(2 | HOT)4 P(3 | HOT) 4 P(1 | COLD)5 P(2 | COLD)4 P(3 COLD) Figure 9.3 A hidden Markov model for relating numbers of ice creams eaten by Jason (the observations) to the weather (H or C, the hidden variables) A) Give an observation sequence with a most probable hidden state sequence that starts with a HOT day and ends with a COLD day. Show your probability calculations. B) Give an observation sequence with a most probable hidden state sequence that starts with COLD day and ends with a HOT day.
