Information Decomposition and Synergy

  title={Information Decomposition and Synergy},
  author={Eckehard Olbrich and Nils Bertschinger and Johannes Rauh},
Recently, a series of papers addressed the problem of decomposing the information of two random variables into shared information, unique information and synergistic information. Several measures were proposed, although still no consensus has been reached. Here, we compare these proposals with an older approach to define synergistic information based on the projections on exponential families containing only up to k-th order interactions. We show that these measures are not compatible with a… CONTINUE READING
