Directed information, $${\displaystyle I(X^{n}\to Y^{n})}$$, is an information theory measure that quantifies the information flow from the random process $${\displaystyle X^{n}=\{X_{1},X_{2},\dots ,X_{n}\}}$$ to the random process $${\displaystyle Y^{n}=\{Y_{1},Y_{2},\dots ,Y_{n}\}}$$. The term … See more Estimating and optimizing the directed information is challenging because it has $${\displaystyle n}$$ terms where $${\displaystyle n}$$ may be large. In many cases, one is interested in optimizing the … See more This law, established by James Massey and his son, gives a very nice intuition to the directed information and its relation to mutual information. The law states that for any See more The essence of directed information is from the causal conditioning operation. The causal conditionng is denoted by $${\displaystyle (\cdot \cdot )}$$.
