TL;DR

This lecture will take a different approach and interpret the entropy as a measure of uncertainty of an experiment with \(n\) possible outcomes, where each outcome will take place with a certain probability.

Abstract

Up to now we had an operational access to the entropy function, i.e., the entropy was involved into the solution of a mathematical problem. More specifically, the entropy turned out to be a measure for data compression. In this lecture we will take a different approach and interpret the entropy as a measure of uncertainty of an experiment with \(n\) possible outcomes, where each outcome will take place with a certain probability. The approach will be axiomatic, i.e., some "reasonable" conditions which a measure of uncertainty should possess are postulated.
