The new method developed by Dr Polani’s team measures redundancy in a system with three variables. This new measure captures many of the intuitive properties of redundancy, with the added bonus of a novel information-geometric interpretation, which has not been done before. It measures how much the information in one variable lies “in the same direction” with respect to the other variable that you want to know more about.

This novel method of measuring redundancy has applications for researchers in a variety of different fields. One immediate use is to track how information flows through a system which promises to be a very valuable tool in neuroscience and the study of networks, agents and other complex scenarios where it is essential to trace the origin and the effects of information flow.
