 A Mathematical Theory of Communication

"A Mathematical Theory of Communication" is a seminal paper written by Claude Shannon, published in 1948. It is widely regarded as the foundation of information theory. In this work, Shannon introduced a rigorous mathematical framework for quantifying information and analyzing communication systems. Key concepts from the theory include: 1. **Information and Entropy**: Shannon defined information in terms of uncertainty and introduced the concept of entropy as a measure of the average information content in a message.
