A Medida de Informação de Shannon: Entropia
DOI:
10.47976/RBHM2021v20n4145-72Palavras-chave:
Entropia, Medidas de informação, Axiomas, Equação funcional, Teoria de ShannonResumo
Logo após Claude E. Shannon, em 1948, ter publicado o artigo A Mathematical Theory of Communication, diversas áreas se valeram de seus escritos, principalmente por ele ter desenvolvido uma fórmula para “medir informação” em seu modelo matemático de comunicação, denominando-a entropia. Shannon optou pela justificativa operacional da existência de sua fórmula de entropia. Por conseguinte, houve uma expansão das áreas de investigações matemáticas sobre as possíveis caracterizações de medidas de informação. Neste texto o objetivo é focar nas estruturas matemáticas que fundamentam o conceito de medidas de informação. Estima-se com isso, no sentido didático, que haja esclarecimentos com relação às múltiplas leituras do conceito de entropia.
