WebAll dyads have the same Harmonic Hartley Entropy. The Hartley Entropy is sometimes called the "max-entropy," and is useful mainly as an upper bound on the other forms of entropy: all Rényi Entropies are always guaranteed to be less than the Hartley Entropy.

Definition (s): The min-entropy (in bits) of a random variable X is the largest value m having the property that each observation of X provides at least m bits of …
WebFeb 3, 2016 · This means that Mathematica calculates entropy using Log base e, which is called nat entropy. With a choice of 2 for the base of the Log you get the Shannon … WebThe Hartley entropy (in the infinite case) is a very sensitive quantity. Although it is true that neither the Shannon nor the v. Neumann entropy are continuous (w.r.t the 1’, or trace norm, resp.) but lower semi-continuous only the continuity properties of the Hartley entropy are by far much worse.
