In information theory, inequalities are mathematical expressions that highlight the relationships between various measures of information. Here are some key inequalities in information theory: 1. **Data Processing Inequality (DPI)**: This states that if \\(X\\) and \\(Y\\) are two random variables, and \\(Z\\) is a random variable that is a function of \\(Y\\) (i.e.
