WebThis is example of weather prediction model using Markov chain " it is a process for which predictions can be made regarding future outcomes based solely on its present state and—most importantly—such predictions are just as good as the ones that could be made knowing the process's full history. " - wikipedia/Markov Chain Markov Chain Diagram WebA Hidden Markov Model can be used to study phenomena in which only a portion of the phenomenon can be directly observed while the rest of it is hidden from direct view. The effect of the unobserved portion can only be estimated. We represent such phenomena using a mixture of two random processes. One of the two processes is a ‘ visible process ’.
