Information 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.

No, information is conserved, and so does not increase. Entropy is incrasing and this means that the evolution goes from ordered universe towards disordered universe, so exacly the contrary of what you are saying. 2020-08-14 the information entropy saturates.) When the message is received, it becomes a deterministi-callyknownrecordofdata.Foranydeterministicallyknown data set the information entropy is zero [4] because then the probabilities in Eq. 3 are either zero or one. Thus the initial information entropy changes to zero SI(1) → 0 and SI(2) → 0(5) 2021-04-17 Note: while relative entropy is not symmetric, mutual information is.

In several socioeconomic applications, matrices containing information on flows-trade, income or migration flows, for example–are usually not constructed from direct observation but are rather estimated, since the compilation of the information required is often extremely expensive and time-consuming.

thus log_2 (p) is a negative value. thus -p * log_2 (p) is a positive value (a negative value times a negative is positive) As a side note -p * log_2 (p) = p * log_2 (1/p) if that form seems more intuitive. Hope this makes sense.

Information entropy

In information theory, a mathematical measure of the degree of randomness in a set of data, with greater randomness impl 2021-03-25 2010-01-27 2020-10-25 The concept of information entropy was introduced by Claude Shannon in his 1948 paper "A Mathematical Theory of Communication", and is sometimes called Shannon entropy in his honour. As an example, consider a biased coin with probability p of landing on heads and probability 1- p of landing on tails.

Recall that the table Comparison of two encodings from M to S showed that the second encoding scheme would transmit an average of 5.7 characters from M per second. But suppose that, instead of the distribution of characters shown in the table, a long series of As were transmitted.
