Webb13 apr. 2024 · It is therefore natural to use Shannon's definition of information, 15 (5) I = log 2 Ω s, I = {\log _2}{\Omega _s}, where Ω s is the number of possible states that the known state was chosen from. This has the same form as the entropy defined above, and is sometimes called “Shannon entropy.” WebbDefining information remains such a contested project that any claim to present a unified, singular vision of the topic would be disingenuous. Seven categories of definitions are described: ... Shannon did not define information at all, at least in any conventionally understandable way.
