Shannon Information
Shannon InformationShannonInformation is a quantifiable notion of what information (or data) is, developed by ClaudeShannon at BellLabs. The idea is that data that you know is going to appear has low information content, and data that surprises you has high information content.
There is a formula: H = log2(1/p(n)).
It's quite cool and radical.
