He has also done work with multi-agent systems, reputation and trust models, and electronic markets.
Darius Braziunas completed his Ph.D. in 2012 on new, effective ways of eliciting, representing and reasoning with user preferences and utility functions. As part of his research, he developed the UTPref Recommendation System that maintains an explicit (but incomplete) multiattribute utility model of user preferences, and uses minimax regret to guide decision-theoretically sound elicitation of preferences and recommendation of options. Other areas of interest include sequential decision making models (MDPs and POMDPs), recommendation systems, collaborative filtering, and discrete optimization. Darius was a Research Scientist at Thoora, Inc. (Toronto) for a time during his Ph.D. studies, and is now a Senior Research Scientist at Kobo, Inc. (Toronto).
