![]() ![]() In that previous article, we had briefly modeled the problem of Part of Speech tagging using the Hidden Markov Model. The state diagram that Peter’s mom gave you before leaving. In case any of this seems like Greek to you, go read the previous article to brush up on the Markov Chain Model, Hidden Markov Models, and Part of Speech Tagging. We want to find out if Peter would be awake or asleep, or rather which state is more probable at time tN+1. Mathematically, we have N observations over times t0, t1, t2. Given the state diagram and a sequence of N observations over time, we need to tell the state of the baby at the current point in time. A state diagram provided by Peter’s mom - who happens to be a neurological scientist - that contains all the different sets of probabilities that you can use to solve the problem defined below.a set of observations, which is basically a sequence containing noise or quiet over time, and.All you can hear are the noises that might come from the room.Įither the room is quiet or there is noise coming from the room. You cannot, however, enter the room again, as that would surely wake Peter up. Once you’ve tucked him in, you want to make sure that he’s actually asleep and not up to some mischief. So there’s this naughty kid Peter and he’s going to pester his new caretaker, you!Īs a caretaker, one of the most important tasks for you is to tuck Peter in bed and make sure he is sound asleep. In case you’ve forgotten the problem we were trying to tackle in the previous article, let us revise it for you.
