first problem that I see is that the diagram uses x1, x2, x3 to denote states, yet x(t) is used elsewhere to denote the hidden state variable at time step t -- i.e. x(t) is a variable that can take on one of the values in a state space S (which here contains x1, x2, x3). Perhaps s1, s2, s3 would be more appropriate as states. Also, quite a few transitions are missing from the diagram. Furthermore, the diagram apparently contains three outputs y1, y2, y3 -- yet not all probabilities are specified through appropriate edges; only three probabilities are given: The probability of observing y1 given that the state is x1 (b1), the probability of observing y2 given state x2 (b2), and the probability of observing y3 given state x3 (b3). Shouldn't the model specify a probability for observing any output given any state, i.e.

I think this diagram is confusing, as one cannot continue from the symbols back to the states. I don't really know what this diagram actually shows. It's a markov model of the first step of a hidden markov process, where the observed symbols are illustrated with states. Is this really helpful? It's not a markov model of the whole process and it's not the hidden markov model... 21: 245: 1088: 1306:
clean. Starting probabilities only need to be assumed and must total 1.00. Regardless of the starting point, one will arrive at the correct probability of what type of day it was. The probabilities can be solved directly using Gaussian Elimination, the Grassmann Algorithm or indirectly using the Power Method, Jacobi's Method, or The Gauss-Seidel Method,Successive Over-Relaxation.

emissions typically uses separate emission priors for each state, the reason being that otherwise the emission parameters would have to be statistically independent of the state sequence, which they are not. Joint conjugate emission priors aren't even typical for mixture models, which are a special case of HMM (with fixed uniform transitions), cf.

I've added the genie-ball-urn model from Rabiner 89 just at the start of the article. People who search for hmm in wikipedia are searching for something understandable. As it is now, research papers about hmms like Rabiner's one are much more understandable and accessible than wikipedia. I think the

Indeed, to my understanding, a factorial HMM is a specific instance of an HMM, such that an exact solution is possible. With K HMM chains, and J possible states for each variable for a FHMM, we need an HMM with JˆK states - which means that a straightforward forward-backward algorithm would quickly

of sequences. This is at least mentioned in the section "Using hidden Markov models". Therefore the sentence "The calculation can however be sped up enormously using the Forward algorithm or the equivalent Backward algorithm" is not consistent in the context of the article and references the wrong

Indeed I wondered about the reference to the Viterbi algorithm for speeding up the calculation of posterior probabilities of an observed sequence. It is my understanding that the forward-backward algorithm calculates the posterior probability of a sequence and the Viterbi calculates the most likely

Moreover, I think there is a problem with the diagram describing state transitions (i.e. the one at the top right), which, as far as I can tell, is supposed to graphically illustrate the probabilistic parameters of an HMM, i.e. the probabilities of state transitions and of making observations. The

The article claims that a "typical Bayesian HMM" has shared priors for its emission parameters. I'd really like to see some references for that. While a shared prior is used in cases like Dirichlet Process priors, the case given here, which uses Normal-(Inverse) Gamma as a conjugate for Gaussian

The concrete example is good; however, the probability of the day being rainy or sunny is stated to be 57% and 43% respectively without giving the basis for the conclusion. These probabilities are dependent solely on the state transition diagram and are not dependent on the output: walk, shop,

Shouldn't that be a mobile phone this day and age. Since it is in a transcluded example (which I think is a very poor choice for plain text content) someone with better transcluded-fu should edit it and maybe just cut and paste it as plain text in the article. No sensible reason for it to be
1988:
The parameters of a hidden Markov model are of two types, transition probabilities and emission probabilities (also known as output probabilities). The transition probabilities control the way the hidden state at time t is chosen given the hidden state at time t − 1 {\displaystyle t-1}.

urn-model is much more readable to someone who has never attended a lecture on markov processes than the current article. I also discussed why people actually use HMMs and why the urn-model is just one possible model. There is some overlap with the current article.

I think a far better reference would be Churchill GA (1989) Stochastic models for heterogeneous DNA sequences. Bull Math Biol 51:79–94, which I think might be the first paper suggesting that a DNA sequence is determined by states in a Markove Model.

In the second sentence we can read:" In a hidden Markov model, the state is not directly visible, but output, dependent on the state, is visible". It's me or it is a little difficult to understand?

Agreed, Plato's cave seems like a bit of a stretch here. Probably a more down-to-earth explanation would be appropriate. Feel free to rework it if you have a better expression. Happy editing,

in the state space? As it is, I think the diagram creates more confusion than it resolves; the second diagram showing the general architecture is what I expect to see in an article on HMMs.

In the second half of the 1980s, HMMs began to be applied to the analysis of biological sequences, in particular DNA. Since then, they have become ubiquitous in the field of bioinformatics.
