Shannon's entropy
Did you know?
WebbIn 1948, Shannon 16,17 proposed an entropy (later known as Shannon entropy) that was then largely applied in information science. The Kolmogorov-Sinai entropy 17 and Renyi entropy, 18 , 19 which were developed on the basis of Shannon’s entropy, are widely used in the nonlinear dynamics of the physical system. WebbTo define entropy, Shannon proposed some axioms that he thought any measure of uncertainty should satisfy and deduced a unique function, up to a multiplicative …

Given a discrete random variable Visa mer Named after Boltzmann's Η-theorem, Shannon defined the entropy Η (Greek capital letter eta) of a discrete random variable $${\textstyle X}$$, which takes values in the alphabet $${\displaystyle {\mathcal {X}}}$$ and is distributed according to Visa mer To understand the meaning of −Σ pi log(pi), first define an information function I in terms of an event i with probability pi. The amount of information acquired due to the observation of … Visa mer Relationship to thermodynamic entropy The inspiration for adopting the word entropy in information theory came from the close resemblance between Shannon's formula and very similar known formulae from statistical mechanics. In Visa mer The core idea of information theory is that the "informational value" of a communicated message depends on the degree to which the content of the message is surprising. If a highly likely event occurs, the message carries very little information.
