Directed information: Estimation and optimization, Overview & Causal conditioning

Directed information is an information theory measure that quantifies the information flow from the random string X n = ( X 1 , X 2 , … , X n ) {\displaystyle X^{n}=(X_{1},X_{2},\dots ,X_{n})} to the random string Y n = ( Y 1 , Y 2 , … , Y n ) {\displaystyle Y^{n}=(Y_{1},Y_{2},\dots ,Y_{n})} . The term directed information was coined by James Massey and…
