Specific-information

In information theory, specific-information is the generic name given to the family of state-dependent measures that in expectation converge to the mutual information. There are currently three known varieties of specific information usually denoted $$I_V$$, $$I_S$$, and $$I_{ssi}$$. The specific-information between a random variable $$X$$ and a state $$Y=y$$ is written as :$$I( X ; Y = y)$$.
