Implicit Training of Virtual Agents [chapter]

Anton Bogdanovych, Marc Esteva, Simeon Simoff, Carles Sierra
Lecture Notes in Computer Science  
This paper provides a brief overview of an implicit training method used for teaching autonomous agents to represent humans in 3D Virtual Worlds without any explicit training efforts being required.  ...  Conclusion We presented the implicit training method and described an approach to implement it using a learning graph. Future work includes further development of this concept and its evaluation.  ...  Implicit Training An important feature of 3D Electronic Institutions is that every human participant is always supplied with a corresponding software agent that communicates the desires of the human to  ...

& Virtual training allows the learning and rehearsal of implicit cues, e.g., trustworthy leading action in an emergency evacuation, that cannot be easily understood through merely reading about situations  ...  Using these results, we obtain optimal parameters for nonverbal cues of trustworthiness, and then can use them to guide agents who evaluate human performance in the same training scenarios.  ...  In the virtual evacuation training, a user tries to lead the crowd agents.  ...
