Shannon entropy derivation
Webb13 juni 2024 · Information entropy was first proposed by Shannon. Assuming an information source I is composed by n different signals I, H (I), the information entropy of I was shown in Equation (1), where denotes frequency of I, E () means mathematical expectation, denotes the base of logarithm. When , the unit of H (I) is bit.

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.
