The group is led by Professor Leen-Kiat Soh with a team of students (undergraduate, M.S. and Ph.D.) who are interested in intelligent agents and multiagent systems.  This group was founded in 2002 and has graduated thus far 5 Ph.D. student, 22 M.S. students, and numerous undergraduate students.  Our research foci in this area include deliberative reflective information gathering, ad hoc team formation, cognitive computing, coalition formation, negotiation, and human scaffolding.  Our work has its applications in computer-aided education, survey informatics, and smart grid.  We have also extended our research work to intelligent data analytics that include image processing and adaptive decision making.

INACTIVE & PAST PROJECTS

 

Smart Grid | Simulation of intelligent agents, both demand and supply-side analyses (Elham Foruzan)

Deliberative Reflective Information Gathering | Observer effect, resource-aware multiagent sensing, large team information sharing, potential-based reward shaping (Dr. Adam Eck)

Survey Informatics | Analyzing Gallup Panel data and Census ATUS data, building self-administered and intelligent survey instruments! Funded by NSF CRN, with collaborators Dr. Allan McCutcheon and Dr. Bob Belli.  (Dr. Adam Eck, Dr. Antje Kirschner) (Supported by NSF)

Computational Unified Learning Model (C-ULM) | A multiagent modeling and simulation of the Unified Learning Model. This framework is to our knowledge the first that investigates sophisticated modeling of learning as a distinct process. We expect our C-ULM to fundamentally impact research in multiagent learning and knowledge transfer, especially when human agents are involved.  (Dr. Duane Shell)
