The Data processing inequality is an information theoretic concept which states that the information content of a signal cannot be increased via a local physical operation. This can be expressed concisely as 'post-processing cannot increase information'.[1] As explained by Kinney and Atwal, the DPI means that information is generally lost (never gained) when transmitted through a noisy channel[2].
