Computational foundations of the human world
Marcus J. Hamilton, Abhishek Yadav, Harrison Hartle +10
Human societies continuously transform scattered information into collective judgments and coordinated action, whether through markets discovering prices, governments allocating re…
Collective AI can amplify tiny perturbations into divergent decisions
Hajime Shimao, Warut Khern-am-nuai, Sung Joo Kim
Large language models are increasingly deployed not as single assistants but as committees whose members deliberate and then vote or synthesize a decision. Such systems are often e…
Unveiling hidden features of social evolution by inferring Langevin dynamics from data
Youngkyoung Bae, Hajime Shimao, Seungwoong Ha +2
Are there hidden dynamical common patterns in the evolution of social and cultural history? While the growing availability of digitized social data invites us to answer this questi…
The Past as a Stochastic Process
David H. Wolpert, Michael H. Price, Stefani A. Crabtree +6
Historical processes manifest remarkable diversity. Nevertheless, scholars have long attempted to identify patterns and categorize historical actors and influences with some succes…
Greetings from a Triparental Planet
Gizem Bacaksizlar, Stefani Crabtree, Joshua Garland +11
In this work of speculative science, scientists from a distant star system explain the emergence and consequences of triparentalism, when three individuals are required for sexual…
Cross Validation Based Model Selection via Generalized Method of Moments
Junpei Komiyama, Hajime Shimao
Structural estimation is an important methodology in empirical economics, and a large class of structural models are estimated through the generalized method of moments (GMM). Trad…
Comparing Fairness Criteria Based on Social Outcome
Junpei Komiyama, Hajime Shimao
Fairness in algorithmic decision-making processes is attracting increasing concern. When an algorithm is applied to human-related decision-making an estimator solely optimizing its…
Two-stage Algorithm for Fairness-aware Machine Learning
Junpei Komiyama, Hajime Shimao
Algorithmic decision making process now affects many aspects of our lives. Standard tools for machine learning, such as classification and regression, are subject to the bias in da…
