Fisher Information Metric as a model-free measure of proximity to criticality in neural systems
Yuewei Du, Alberto Liardi, Hardik Rajpal +1
Critical phenomena are widespread across many disciplines and have recently become a topic of deep interest in the study of biological and artificial neural networks. A distinct si…
Emergent Generalization by Representation Learning in Artificial Neural Networks
Hardik Rajpal, Dan Goodman
Dimensionality reduction has proven powerful for identifying neural manifolds, which are low-dimensional structures underlying high-dimensional neural activity. These low-dimension…
Improved estimators of causal emergence for large systems
Madalina I. Sas, Fernando E. Rosas, Hardik Rajpal +3
A central challenge in the study of complex systems is the quantification of emergence -- understood as the ability of the system to exhibit collective behaviours that cannot be tr…
A scalable estimator of higher-order information in complex dynamical systems
Alberto Liardi, George Blackburne, Hardik Rajpal +2
Our understanding of complex systems rests on our ability to characterise how they perform distributed computation and integrate information. Advances in information theory have in…
Quantifying Hierarchical Selection
Hardik Rajpal, Clem von Stengel, Pedro A. M. Mediano +4
At what level does selective pressure effectively act? When considering the reproductive dynamics of interacting and mutating agents, it has long been debated whether selection is…
Synergistic Small Worlds that Drive Technological Sophistication
Hardik Rajpal, Omar A Guerrero
Advanced economies exhibit a high degree of sophistication in the creation of various products. While critical to such sophistication, the nature and underlying structure of the in…
Tangled Worldview Model of Opinion Dynamics
Hardik Rajpal, Fernando Rosas, Henrik Jeldtoft Jensen
We study the joint evolution of worldviews by proposing a model of opinion dynamics, which is inspired in notions from evolutionary ecology. Agents update their opinion on a specif…
