Deep Generative Modeling in Network Science with Applications to Public Policy Research

Gavin S. Hartnett, Raffaele Vardavas, Lawrence Baker +5

Network data is increasingly being used in quantitative, data-driven public policy research. These are typically very rich datasets that contain complex correlations and inter-depe…

A Generative Machine Learning Approach to Policy Optimization in Pursuit-Evasion Games

Shiva Navabi, Osonde A. Osoba

We consider a pursuit-evasion game [11] played between two agents, 'Blue' (the pursuer) and 'Red' (the evader), over time steps. Red aims to attack Blue's territory. Blue's obj…

Policy-focused Agent-based Modeling using RL Behavioral Models

Osonde A. Osoba, Raffaele Vardavas, Justin Grana +2

Agent-based Models (ABMs) are valuable tools for policy analysis. ABMs help analysts explore the emergent consequences of policy interventions in multi-agent decision-making settin…

Steps Towards Value-Aligned Systems

Osonde A. Osoba, Benjamin Boudreaux, Douglas Yeung

Algorithmic (including AI/ML) decision-making artifacts are an established and growing part of our decision-making ecosystem. They are indispensable tools for managing the flood of…

Beyond DAGs: Modeling Causal Feedback with Fuzzy Cognitive Maps

Osonde Osoba, Bart Kosko

Fuzzy cognitive maps (FCMs) model feedback causal relations in interwoven webs of causality and policy variables. FCMs are fuzzy signed directed graphs that allow degrees of causal…

Noisy Expectation-Maximization: Applications and Generalizations

Osonde Osoba, Bart Kosko

We present a noise-injected version of the Expectation-Maximization (EM) algorithm: the Noisy Expectation Maximization (NEM) algorithm. The NEM algorithm uses noise to speed up the…
