Shannon measure of information
Webb1 maj 2024 · Abstract Shannon entropy has long been accepted as a primary basis for assessing the information content of sensor channels used for the remote sensing of atmospheric variables. It is not widely appreciated, however, that Shannon information content (SIC) can be misleading in retrieval problems involving nonlinear mappings … WebbThe well-known Shannon measure of information emerges in several models, sometimes as a cost measure, sometimes as a benefit measure. An alterna- tive approach starts with Bayesian normal sampling; it tends to use as its preferred measure of information the precision of a distribution, defined as the reciprocal

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.
