WebbShannon entropy (or just entropy) is a measure of uncertainty (or variability) associated with random variables. It was originally developed to weigh the evenness and richness of animal and plant species (Shannon, 1948).

Information and Entropy // University of Oldenburg
Shannon's theory defines a data communication system composed of three elements: a source of data, a communication channel, and a receiver. The "fundamental problem of communication" – as expressed by Shannon – is for the receiver to be able to identify what data was generated by the … Visa mer In information theory, the entropy of a random variable is the average level of "information", "surprise", or "uncertainty" inherent to the variable's possible outcomes. 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 … 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 WebbThe Shannon entropy is a standard measure for the order state of sequences. It quantifies the degree of skew of the distribution of values. Increasing hypnotic drug concentrations increase electroencephalographic amplitude.
