Cover Story: Partial information decomposition (PID) and information deltas are two frameworks, each based in information theory, which seek to detect and characterize non-pairwise relationships between variables. This paper unites these frameworks, equating their key expressions. This allows for results in one framework to give insights toward open questions in the other. Furthermore, PID solutions can be mapped onto the space of Delta measures, with its well-characterized geometry. There is no universally accepted solution for PID computation, and this mapping distinguishes at a glance how putative solutions decompose information. We demonstrate this by computing and mapping the solutions of both Bertschinger et al. and Finn et al. for all three-variable, three-letter discrete functions. View this paper

Classical option pricing schemes assume that the value of a financial asset follows a geometric Brownian motion (GBM). However, a growing body of studies suggest that a simple GBM trajectory is not an adequate representation for asset dynamics, due t...
