Shannon Entropy Calculator Explanation


Shannon entropy, or more formally information entropy, is a key idea in information theory, a branch of research that is concerned with quantifying the information used in communication. Entropy often refers to the disorder or uncertainty within a system in thermodynamics and other sciences. Information entropy was first proposed by Claude Shannon in the late 1940s, and today's definition is practically identical to that of thermodynamics. The idea of information entropy is now used in a variety of contexts, including security, encryption, and even artificial intelligence and machine learning. Information entropy is defined mathematically as follows:
