Abstract: Proposed work reviews the research and development of HMM, in finding out the mobility patterns and keeping the main focus on the state-of-the-art. Concepts related to Markov chains are explained and then the ideas are extended to the class of HMMs using several simple examples. The mathematics of the HMM is presented, beginning with the Markov chain and then including the three main constituent algorithms: the Viterbi algorithm, the forward algorithm, and the Baum-Welch. Throughout the text, the description of the theory is intertwined with real-world applications.

Keywords: hidden Markov model; human mobility pattern; Viterbi algorithm; forward algorithm; Baum-Welch algorithm.
