Pulses, waves, and cascades in collective migration dynamics
Niraj Kushwaha, Woi Sok Oh, Edward D. Lee
Decisions to migrate depend on others' decisions. Dependence can produce nontrivial dynamics. We propose a minimal migration model that accounts for social influence alongside indi…
Collective contributions to polarized voting
Edward D. Lee
The crux of polarized voting in institutions like legislatures or courts is separation along a unidimensional ideological axis, but voting behavior is in reality more complex, with…
Common indicators hurt armed conflict prediction
Niraj Kushwaha, Woi Sok Oh, Shlok Shah +1
Are big conflicts different from small or medium size conflicts? To answer this question, we leverage fine-grained conflict data, which we map to climate, geography, infrastructure…
Innovation-exnovation dynamics on trees and trusses
Edward D. Lee, Ernesto Ortega-Díaz
Innovation and its complement exnovation describe the progression of realized possibilities from the past to the future, and the process depends on the structure of the underlying…
Closely estimating the entropy of sparse graph models
Edward D. Lee
We introduce an algorithm for estimating the entropy of pairwise, probabilistic graph models by leveraging bridges between social communities and an accurate entropy estimator on s…
Discovering the mesoscale for chains of conflict
Niraj Kushwaha, Edward D. Lee
Conflicts, like many social processes, are related events that span multiple scales in time, from the instantaneous to multi-year developments, and in space, from one neighborhood…
Information consumption and size in firms
Edward D. Lee, Alan P. Kwan, Rudolf Hanel +2
Social and biological collectives need to exchange information to persist and to function. This happens across internal networks, whose structure represents static channels through…
Outsourcing Memory Through Niche Construction
Edward D. Lee, Jessica C. Flack, David C. Krakauer
Adaptation to changing environments is a universal feature of life and can involve the organism modifying itself in response to the environment as well as actively modifying the en…
Idea engines: Unifying innovation and obsolescence from markets and genetic evolution to science
Edward D. Lee, Christopher P. Kempes, Geoffrey B. West
Innovation and obsolescence describe dynamics of ever-churning and adapting social and biological systems, concepts that encompass field-specific formulations. We formalize the con…
Discovering sparse control strategies in C. elegans
Edward D. Lee, Xiaowen Chen, Bryan C. Daniels
Biological circuits such as neural or gene regulation networks use internal states to map sensory input to an adaptive repertoire of behavior. Characterizing this mapping is a majo…
Dynamics of growth, death, and resource competition in sessile organisms
Edward D. Lee, Christopher P. Kempes, Geoffrey B. West
Population-level scaling in ecological systems arises from individual growth and death with competitive constraints. We build on a minimal dynamical model of metabolic growth where…
Sensitivity of collective outcomes identifies pivotal components
Edward D. Lee, Daniel M. Katz, Michael J. Bommarito +1
A social system is susceptible to perturbation when its collective properties depend sensitively on a few pivotal components. Using the information geometry of minimal models from…
Emergent regularities and scaling in armed conflict data
Edward D. Lee, Bryan C. Daniels, Christopher R. Myers +2
Armed conflict exhibits regularities beyond known power law distributions of fatalities and duration over varying culture and geography. We systematically cluster conflict reports…
Convenient Interface to Inverse Ising (ConIII): A Python 3 Package for Solving Ising-Type Maximum Entropy Models
Edward D. Lee, Bryan C Daniels
ConIII (pronounced CON-ee) is an open-source Python project providing a simple interface to solving the pairwise and higher order Ising model and a base for extension to other maxi…
Strong consensus on US Supreme Court spans a century
Edward D. Lee
The US Supreme Court throughout the 20th century has been characterized as being divided between liberals and conservatives, suggesting that justices with similar ideologies would…
Deformation of crystals: Connections with statistical physics
James P. Sethna, Matthew K. Bierbaum, Karin A. Dahmen +12
We give a bird's-eye view of the plastic deformation of crystals aimed at the statistical physics community, and a broad introduction into the statistical theories of forced rigid…
Capturing collective conflict dynamics with sparse social circuits
Edward Lee, Bryan Daniels, Jessica Flack +1
We discuss a set of computational techniques, called Inductive Game Theory, for extracting strategic decision-making rules from time series data and constructing probabilistic soci…
Statistical mechanics of the US Supreme Court
Edward D. Lee, Chase P. Broedersz, William Bialek
We build simple models for the distribution of voting patterns in a group, using the Supreme Court of the United States as an example. The least structured, or maximum entropy, mod…
