nice right?Īs an exercise, please come up with your own real-life example. You can calculate the transition probability and have a very basic model to predict the weather… I am not sure how accurate it will be, but you can say you used a Markov Chain to predict the weather…. You could simply replace A and B for S and R on the previous model. Now on a more realistic example, say you want to predict the weather and you start to write down the weather daily on a very simple way, you go “S” for sunny and “R” for rainy. If you were to observe this model for awhile and write down a long chain, you would eventually realize that some transitions happen more than others and you could then take the ratio of the number for a particular transition (say AB) and divide it by all the transitions you observe, that is called a transition probability. So, the model would produce a Markov Chain that would look something like: AABBBABBBAAABBB etc.Īs an exercise, please follow the dot (if you don’t see the dot moving, you may need to open the document in MS word) and produce your own Markov Chain out this model mine is:ĪABBBBAABBBAABBBBAABAAAAA is your similar?Įvery time the dot moves, that is call a transition. You can also notice that the model can go from A to B or from A back to A.

There are a couple of things to notice here: this model has two states, “A” and “B”. This a very basic representation of a Markov Chain: We’ve already talked about Markov chains, but let’s review briefly. That’s why an HMM is called an HMM – it’s a “hidden Markov model” that relies on a Markov chain where you can’t see the states, only the results of a state transition. Basically, the way this works is you start with a Markov chain, and if the Markov chain doesn’t completely “work” or create a model that’s predictable, you can assume that there is a “hidden” component that is required to make a more accurate model. In an HMM, what are Hidden States? If they are truly hidden, how can we determine what they are? Hidden Markov Models (HMM)s:Īn HMM is a way to represent a real-life problem within a statistical framework – creating a model of a process that you may not know all of the variables for, like flipping a coin that isn’t fair, or mutations at a base position of DNA.

Just as we did in the lecture notes, come up with a simple, real-world example of a series of transitions that can be represented as a Markov chain transmission series ( different example in the attachment below)Ģ.
