The hierarchical hidden Markov model (HHMM) is a statistical model derived from the hidden Markov model (HMM). In an HHMM, each state is considered to be a self-contained probabilistic model. More precisely, each state of the HHMM is itself an HHMM. HHMMs and HMMs are useful in many fields, including pattern recognition. (Wikipedia).
Hidden Markov Model Clearly Explained! Part - 5
So far we have discussed Markov Chains. Let's move one step further. Here, I'll explain the Hidden Markov Model with an easy example. I'll also show you the underlying mathematics. #markovchain #datascience #statistics For more videos please subscribe - http://bit.ly/normalizedNERD Mar

Everything you need to know about Machine Learning!
Here is an introduction to Machine Learning. Instead of developing algorithms for every task and subtask to solve a problem, Machine Learning involves teaching a computer to teach itself. There are different types of machine learning problems we may come across. TYPES OF MACHINE LEARNING
