Markov condition
WebThe causal Markov condition is closely related to Reichenbach's principle. Roughly, it says that if C is a set of ancestors to A and B and if A and B are not directly causally … WebA Markov process is a random process for which the future (the next step) depends only on the present state; it has no memory of how the present state was reached. A typical example is a random walk (in two dimensions, the drunkards walk). The course is concerned with Markov chains in discrete time, including periodicity and recurrence.

The Markov condition, sometimes called the Markov assumption, is an assumption made in Bayesian probability theory, that every node in a Bayesian network is conditionally independent of its nondescendants, given its parents.
