How does 'Elements of Information Theory' approach the concept of entropy?

'Elements of Information Theory' by Thomas M. Cover and Joy A. Thomas approaches the concept of entropy as a fundamental measure of uncertainty or randomness in information systems. The authors define entropy in the context of Shannon's information theory, where it quantifies the average amount of information produced by a stochastic source of data. The book elaborates on the mathematical formulation of entropy, specifically the Shannon entropy, which is expressed in terms of probability distributions. It emphasizes how entropy captures the unpredictability of information content and serves as a crucial concept for understanding various applications, such as data compression and communication. Additionally, the authors explore different forms of entropy, including joint entropy, conditional entropy, and relative entropy (Kullback-Leibler divergence), discussing their significance and interrelationships. Through examples and exercises, the book aims to provide a comprehensive understanding of entropy's role in measuring information and guiding decisions in the presence of uncertainty.
