Conditional entropy
The conditional entropy measures how much entropy a random variable X ... prior information information about X . The conditional entropy is just the Shannon entropy with p ( x ∣ y ) ... p ( x ∣ y ) p ( y ) , one finds that the conditional entropy is equal to H(X|Y) = H(X,Y) - H(Y) with "H(XY)" the joint ...
