Webb30 nov. 2024 · Why Shannon Entropy Has Its Formula The formula for entropy, i.e. the Sum of -p i log 2 (p i ) for all symbols, is not aribitrary. As Shannon proves in the appendix to his paper, the entropy must be this formula if we require it to have some natural properties (technically it is up to some constant of proportionality, but we just take it to be 1 for … http://sefidian.com/2024/09/06/shannon-entropy-and-its-properties/
