Mutual information: Applications, Measurement & Art

In probability theory and information theory, the mutual information (MI) of two random variables is a measure of the mutual dependence between the two variables. More specifically, it quantifies the "amount of information" (in units such as shannons (bits), nats or hartleys) obtained about one random variable by observing the other random variable. The…

How Mutual information connects Entity context

The extracted context around Mutual information shows recurring relationship patterns in the source. For example, Mutual information → form of weighted KL-Divergence, hartley, Kullback, measure of the inherent dependence expressed in the joint distribution of X, nat, same as the uncertainty contained in Y, shannon Another extracted example is Mutual information → Approximations, Cilibrasi, Kolmogorov, Li, Using, Vitányi. Use these groups to spot repeated connection types before inspecting the individual relationships.
