This property is expressed by the rows of the transition matrix being … WebThe rich theory of Markov processes is the subject of many text books and one can easily teach a full course on this subject alone. Thus, we limit ourselves here to the deﬁnition of Markov processes and to their most basic properties. For more on Markov chains and processes, see [Bre92, Section 7] and [Bre92, Section 15], respectively.

WebMarkov Chains are another class of PGMs that represents a dynamic process. That is, a process which is not static but rather changes with time. In particular, it concerns more about how the state of a process changes with time. Let’s make it clear with an example.
