Herein, the Hidden Markov Model is expanded to allow for Markov chain observations. In particular, the observations are assumed to be a Markov chain whose one step transition probabilities depend upon the hidden Markov chain. An Expectation-Maximization analog to the Baum-Welch algorithm is developed for this more general model to estimate the transition probabilities for both the hidden state and for the observations as well as to estimate the probabilities for the initial joint hidden-state-observation distribution. A believe state or filter recursion to track the hidden state then arises from the calculations of this Expectation-Maximization algorithm. A dynamic programming analog to the Viterbi algorithm is also developed to estimate the most likely sequence of hidden states given the sequence of observations.

Intel (INTC) is a name everyone knows; with a market cap over $200 billion, it's the world's largest semiconductor maker, notes growth stock expert Rich Suttmeier, editor of 2-Second Trader. The company dominates the processor market for desktop PCs, laptops, and servers. And trends like cloud computing and artificial intelligence are creating new growth markets for Intel to target. Intel reported its latest quarterly results about a month ago -- on July 23. Revenue and earnings per share (EPS) were both above analysts' estimates.
