Agent-Based Model Calibration using Machine Learning Surrogates [PDF]
, 2017 Taking agent-based models (ABM) closer to the data is an open challenge. This paper explicitly tackles parameter space exploration and calibration of ABMs combining supervised machine-learning and intelligent sampling to build a surrogate meta-model. The

Agent‐Based Modeling and Simulation
AI Magazine, 2012 This article gives an introduction to agent‐based modeling and simulation (ABMS). After a general discussion about modeling and simulation, we address the basic concept of ABMS, focusing on its generative and bottom‐up nature, its advantages as well as its pitfalls.

Data-driven modeling of collaboration networks: a cross-domain analysis
EPJ Data Science, 2017 We analyze large-scale data sets about collaborations from two different domains: economics, specifically 22,000 R&D alliances between 14,500 firms, and science, specifically 300,000 co-authorship relations between 95,000 scientists.

An information theory based behavioral model for agent-based crowd simulations [PDF]
, 2010 Crowds must be simulated believable in terms of their appearance and behavior to improve a virtual environment’s realism. Due to the complex nature of human behavior, realistic behavior of agents in crowd simulations is still a challenging problem.

Validation and Calibration of an Agent-Based Model: A Surrogate Approach
Discrete Dynamics in Nature and Society, 2020 Agent-based modelling has been proved to be extremely useful for learning about real world societies through the analysis of simulations. Recent agent-based models usually contain a large number of parameters that capture the interactions among ...

À la recherche d’effets réseaux dans la dynamique du modèle de ségrégation de Schelling
Cybergeo, 2010 It is a shared belief that Thomas Schelling’ model of segregation is only weakly affected by the underlying spatial structure, whatever its complexity.

Optimal Inflation Target: Insights from an Agent-Based Model [PDF]
, 2017 Which level of inflation should Central Banks be targeting? We investigate this issue in the context of a simplified Agent Based Model of the economy. Depending on the value of the parameters that describe the behaviour of agents (in particular inflation

Post-earthquake modelling of transportation networks using an agent-based model [PDF]
Structure and Infrastructure Engineering, 2018 Surface transportation systems are an essential part of urban transportation infrastructure and are susceptible to damage from earthquakes. This damage, along with the lack of prior warning of earthquake events, may lead to severe and unexpected ...
