Webb24 mars 2015 · This parallel wasn't lost on Shannon. He called the measure of average information defined above the entropy of the machine. It depends only on the probability distribution of the possible symbols, the exact workings of the mechanism producing it don't matter. Entropy is a truly universal measure of information. WebbBiodiversity - The number of different species of organisms in a particular environment. Evenness (E) - A measure of how similar the abundances of different species are in the community. Shannon-Weiner index (H) - This diversity measure came from information theory and measures the order (or disorder) observed within a particular system.

WebbThere are thus various measures of or related to information all of which may use the shannon as a unit.
