In this paper, we propose a new framework for learning Granger causality from multi-animal trajectories via augmented theory-based behavioral models with interpretable data-driven models.  ...  We adopt an approach for augmenting incomplete multi-agent behavioral models described by time-varying dynamical systems with neural networks.  ...  For obtaining flies data, we would like to thank Ryota Nishimura at Nagoya University.  ...

How to design agent-based simulation models using agent learning

Robert Junges, Franziska Klugl
2012 Proceedings Title: Proceedings of the 2012 Winter Simulation Conference (WSC)  
Results demonstrate the agents can learn and report back to the modeler a behavior that is interestingly better than a hand-made model.  ...  In this contribution we introduce the MABLe methodology for analyzing and designing agent simulation models that relies on adaptive agents, where the agent helps the modeler by proposing a suitable behavior  ...  Figure 2 : 2 Behavior trees for different objective function details putting more focus on collision avoidance or fast evacuation.  ...

A biologically inspired learning mechanism allows the neural network to adapt during the lifetime of a creature. Learning includes the ability to acquire a simple verb-object language.  ...  Each creature has a neural network responsible for sensory-motor coordination and behavior selection, and an "artificial biochemistry" that models a simple energy metabolism along with a "hormonal" system  ...  In keeping with standard biology terminology, we refer to a neuron's input-connections as 'dendrites'.  ...

Learn to Interpret Atari Agents [article]

Zhao Yang and Song Bai and Li Zhang and Philip H.S. Torr
2019 arXiv   pre-print
However, the direct mapping from states to actions makes it hard to interpret the rationale behind the decision making of agents.  ...  RS-Rainbow utilizes a simple yet effective mechanism to incorporate visualization ability into the learning model, not only improving model interpretability, but leading to improved performance.  ...  In this work, we approach from a learning perspective, and propose Region Sensitive Rainbow (RS-Rainbow) to improve both the interpretability and performance of a DeepRL model.  ...

Observer effect from stateful resources in agent sensing

Adam Eck, Leen-Kiat Soh
2012 Autonomous Agents and Multi-Agent Systems  
In this model, the agent uses reinforcement learning to learn a controller for action selection, as well as how to predict expected knowledge refinement based on resource use during sensing.  ...  In many real-world applications of multi-agent systems, agent reasoning suffers from bounded rationality caused by both limited resources and limited knowledge.  ...  Acknowledgments We would like to thank the anonymous reviewers for their constructive feedback and helpful suggestions, which were used to improve the presentation of this research.  ...

Differentiable Agent-based Epidemiology [article]

Ayush Chopra, Alexander Rodríguez, Jayakumar Subramanian, Balaji Krishnamurthy, B. Aditya Prakash, Ramesh Raskar
2022 arXiv   pre-print
Agent-based models (ABMs) are an increasingly popular alternative paradigm that can represent the heterogeneity of contact interactions with granular detail and agency of individual behavior.  ...  Mechanistic simulators are an indispensable tool for epidemiology to explore the behavior of complex, dynamic infections under varying conditions and navigate uncertain environments.  ...  Conventional ABM frameworks follow an object-oriented (agent-centered) design where the agents are modeled as objects.  ...

2003 Complexity  
The observed results are not sensitive to changes in the parameter values.  ...  The model consists of autonomous, interactive agents that buy stock on a financial market. Transaction decisions are based on a number of individual and collective elements.  ...  We first introduce the model and explain how each agent is modelled and how their interaction results in the overall market behavior.  ...
