Webb29 aug. 2013 · This measure, which is based on the Shannon entropy, is well suited for the given purpose. Finally, we outline a generic model of quantitative complexity scale for ASC Networks. ... Both theories use the same unit—the bit— for measuring information. Shannon’s entropy has been generalized in different directions. In information theory and derivative fields such as coding theory, one cannot quantify the "information" in a single message (sequence of symbols) out of context, but rather a reference is made to the model of a channel (such as bit error rate) or to the underlying statistics of an information source. There are thus various measures of or related to information all of which may use the shannon as a unit.
