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 … 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 … 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. On … 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. The entropy of the unknown result of the next toss of the coin is maximized if the coin is fair (that is, if … Visa mer The Shannon entropy satisfies the following properties, for some of which it is useful to interpret entropy as the expected amount of … Visa mer philly pretzel factory academy road
