The concept of **entropy rate** is rooted in information theory and is used to measure the average information production rate of a stochastic (random) process or a data source. In detail: 1. **Information Theory Context**: Entropy, introduced by Claude Shannon, quantifies the uncertainty or unpredictability of a random variable or source of information. The entropy \( H(X) \) of a discrete random variable \( X \) with possible outcomes \( x_1, x_2, ...
