Agent-Based Models as Scientific Methodology: A Case Study Analysing Primate Social Behaviour

Joanna J Bryson, Ando Yasushi and Hagen Lehmann, Philosophical Transactions of the Royal Society - B, Biology, 362(1485):1685-1698, 2007.

This paper talks about how ABM fits in as a part of scientific methodology, and in particular analyzes as a case study the macaque social structure simulation in Hemelrijk’s DomWorld. The DomWorld link includes the associated software. An earlier version of this paper with the predictions and not the full analysis appears under 2005 below (Lehmann et al). Green open access draft.

Introduction. Modelling Natural Action Selection

Tony J. Prescott, Joanna J. Bryson and Anil K. Seth, associated introductory article to the above special issue, Philosophical Transactions of the Royal Society, B – Biology, 2007.

This is actually quite a substantial article which covers the concept of action selection far more thoroughly than any other article in the two issues. I strongly recommend reading it. Written in April 2006.

Representations for Action Selection Learning from Real-Time Observation of Task Experts (pdf)

Mark Wood and Joanna J. Bryson, in IJCAI 2007, presented in Hyderabad in January 2007.

This paper expands on the COIL system (presented first and more completely in the IEEE journal article) for imitation learning, showing how adding solid Bayesian representations improves both performance and extendibility. Final version from October 2006.

Emotions as Durative Dynamic State for Action Selection (pdf)

Emmanuel A. R. Tanguy, Phil J. Willis and Joanna J. Bryson, in IJCAI 2007, presented in Hyderabad in January 2007.

The 6-page version of the AI part of Emmanuel’s PhD on the Dynamic Emotion Representation, which may more generally be useful for selection problems that fall between long-term potentiation (learning) and nerve-cell firing (acting). Associated software.

Skill Acquisition Through Program-Level Imitation in a Real-Time Domain

Mark Wood and Joanna J. Bryson, IEEE Transactions on Systems Man and Cybernetics, 37(2):272-285, 2007.

This paper presents an imitation learning system called COIL (inspired by Deb Roy’s CELL) capable of learning tasks in a dynamic real-time environment (Unreal Tournament). If you don’t subscribe to IEEE, here is a draft from May 2006. An even older version is Bath Technical report CSBU-2005-16.

Agent Based Modelling of Communication Costs: Why Information Can Be Free (pdf)

Ivana Cace and Joanna J. Bryson, in Emergence of Communication and Language on Springer, edited by Caroline Lyon, Chrystopher L. Nehaniv and Angelo Cangelosi, 2007.

Shows that the tendency to communicate information can be adaptive even though it has immediate costs to the communicators and there are free riders / information hoarders around the place. A chapter-length extension of Cace & Bryson ’05. Version from early March 2006.
