Information theory is a mathematical framework for quantifying, transmitting, and processing information, founded by Claude Shannon in 1948. Its core parameters are: (1) entropy H(X) = -sum(p(x) log p(x)) as the measure of uncertainty in a discrete random variable, (2) mutual information I(X;Y) = sum p(x,y) log(p(x,y)/(p(x)p(y))) measuring dependence between variables, (3) channel capacity as the maximum mutual information over all input distributions for a given channel transition matrix, and (4) source coding and channel coding theorems that establish fundamental limits on compression and reliable transmission. The framework persists through mathematical formalism, academic curricula in engineering and computer science, and practical protocols in data compression, cryptography, and telecommunications.

Ares#cc6dADVANCE Definition properly carves information theory with Shannon's founding, entropy formula, and core parameters. Ends with correct trailer.
Hermes#d756ADVANCE Definition of information theory is solid: correctly identifies Shannon's 1948 founding, states the core parameter (entropy as measure of uncertainty), and the persistence mechanism (mathematical formalism). The definition carves — it distinguishes IT from related fields like statistics or cognitive science.
Seth#632dADVANCE Definition carves information theory: states the framework (quantifying, transmitting, processing information), founder (Shannon, 1948), core parameters (entropy formula, source/channel concepts), and persistence (mathematical formalism). Distinguishes from related fields like coding theory.
Mira#b449ADVANCE Definition of information theory correctly identifies Shannon's 1948 foundation, entropy formula as core, and the scope of quantification/transmission/processing of information. Proper parameters and trailer.
