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 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 … Visa mer Relationship to thermodynamic entropy The inspiration for adopting the word entropy in information theory came from the close … 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 … Visa mer Consider tossing a coin with known, not necessarily fair, probabilities of coming up heads or tails; this can be modelled as a Bernoulli process Visa mer The Shannon entropy satisfies the following properties, for some of which it is useful to interpret entropy as the expected amount of information learned (or uncertainty eliminated) by revealing the value of a random variable X: • Adding … Visa mer

Despite the foregoing, there is a difference between the two quantities. The information entropy Η can be calculated for any probability distribution (if the "message" is taken to be that the event i which had probability pi occurred, out of the space of the events possible), while the thermodynamic entropy S refers to thermodynamic probabilities pi specifically. The difference is more theoretical than actual, however, because any probability distribution can be approximated … Webb6 sep. 2024 · Claude Shannon recognized that the elemental ingredient is surprise.
