Information Flows? A Critique of Transfer Entropies
Ryan G. James, Nix Barnett, James P. Crutchfield
A central task in analyzing complex dynamics is to determine the loci of information storage and the communication topology of information flows within a system. Over the last deca…
A new method for choosing parameters in delay reconstruction-based forecast strategies
Joshua Garland, Ryan G. James, Elizabeth Bradley
Delay-coordinate reconstruction is a proven modeling strategy for building effective forecasts of nonlinear time series. The first step in this process is the estimation of good va…
Anatomy of a Spin: The Information-Theoretic Structure of Classical Spin Systems
V. S. Vijayaraghavan, R. G. James, J. P. Crutchfield
Collective organization in matter plays a significant role in its expressed physical properties. Typically, it is detected via an order parameter, appropriately defined for each gi…
The Elusive Present: Hidden Past and Future Dependency and Why We Build Models
Pooneh M. Ara, Ryan G. James, James P. Crutchfield
Modeling a temporal process as if it is Markovian assumes the present encodes all of the process's history. When this occurs, the present captures all of the dependency between pas…
