An Agent-Based Classification Model [PDF]
SSRN Electronic Journal, 2007 The major function of this model is to access the UCI Wisconsin Breast Can- cer data-set[1] and classify the data items into two categories, which are normal and anomalous. This kind of classifi cation can be referred as anomaly detection, which discriminates anomalous behaviour from normal behaviour in computer systems.

Statistical Mechanics of Political Polarization
Entropy, 2022 Rapidly increasing political polarization threatens democracies around the world. Scholars from several disciplines are assessing and modeling polarization antecedents, processes, and consequences. Social systems are complex and networked. Their constant

Agent-Based Model Exploration [PDF]
, 2015 The previous chapters have allowed us to introduce the basics of agent-based model creation with NetLogo. This has resulted in a model such as the one used in our running example. Once the model has been built, the aim is to manipulate it in such a way that new knowledge about the modeled phenomenon can be created.

Empirically Based, Agent-based models
Ecology and Society, 2006 There is an increasing drive to combine agent-based models with empirical methods. An overview is provided of the various empirical methods that are used for different kinds of questions.

Œconomia, 2020 This paper presents an overview of how agent-based computational economics can contribute to the study of economic systems. It highlights the way these models can improve our understanding of social interactions and coordination mechanisms and bring to ...

Voter-like Dynamics with Conflicting Preferences on Modular Networks
Entropy, 2023 Two of the main factors shaping an individual’s opinion are social coordination and personal preferences, or personal biases. To understand the role of those and that of the topology of the network of interactions, we study an extension of the voter ...

Agent-Based Pedestrian Modeling [PDF]
Environment and Planning B: Planning and Design, 2001 When the focus of interest in geographical systems is at the very fine scale, at the level of streets and buildings for example, movement becomes central to simulations of how spatial activities are used and develop. Recent advances in computing power and the acquisition of fine scale digital data now mean that we are able to attempt to understand ...

Agent-based Models of Financial Markets [PDF]
, 2007 This review deals with several microscopic (``agent-based'') models of financial markets which have been studied by economists and physicists over the last decade: Kim-Markowitz, Levy-Levy-Solomon, Cont-Bouchaud, Solomon-Weisbuch, Lux-Marchesi, Donangelo-

Frontiers in Immunology, 2015 Agent-based modeling has been used to characterize the nested control loops and nonlinear dynamics associated with inflammatory and immune responses, particularly as a means of visualizing putative mechanistic hypotheses.

Dynamic calibration of agent-based models using data assimilation [PDF]
Royal Society Open Science, 2016 A widespread approach to investigating the dynamical behaviour of complex social systems is via agent-based models (ABMs). In this paper, we describe how such models can be dynamically calibrated using the ensemble Kalman filter (EnKF), a standard method
