摘要: Multivariate information decompositions hold promise to yield insight into complex systems, and stand out for their ability identify synergistic phenomena. However, the adoption of these approaches has been hindered by there being multiple possible decompositions, no precise guidance preferring one over others. At heart this disagreement lies absence a clear operational interpretation what is. Here we fill gap proposing new decomposition based on novel operationalisation informational synergy, which leverages recent developments in literature data privacy. Our is defined any number sources, its atoms can be calculated using elementary optimisation techniques. The provides natural coarse-graining that scales gracefully with system's size, applicable wide range scenarios practical interest.
