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, and intelligent data analysis.  This group was founded in 2002 and has graduated thus far 5 Ph.D. student, 22 M.S. students, and several 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. Our projects have also included intelligent image analysis.

 

Current Projects

 

Aida Intelligent Image Analysis on Poem Identification | Building an intelligent system to automatically identify poems in old newspapers.  (Yi Liu, Chulwoo (Mike) Pack, Dr. Liz Lorang)  (Supported by NEH and IMLS)

Ad Hoc Team Formation | Considering environmental openness and learning, how should one form teams in an ad hoc environment?  Initial work was done in collaboration with Dr. Raj Dasgupta and Jumadinova.  (Dr. Adam Eck, Dr. Prashant Doshi) (Supported by UCARE)

Adaptive Decision Making |  Analyzing and understanding decision making in blue jays (Dr. Jeff Stevens) (Supported by NSF)

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)
