WebbInformation entropy is a concept from information theory.It tells how much information there is in an event.In general, the more certain or deterministic the event is, the less information it will contain. More clearly stated, information is an increase in uncertainty or entropy. The concept of information entropy was created by mathematician Claude … WebbThe Shannon entropy equation provides a way to estimate the average minimum number of bits needed to encode a string of symbols, based on the frequency of the symbols. It is given by the formula H = - \sum (\pi log (\pi)) H = −∑(πlog(π)) where \pi π is the probability of character number i showing up in a stream of characters of the ...
