In Proceedings of the 18th annual ACM symposium on User interface software and technology (UIST '05), Seattle, WA, October 23-25, 2005: 173-182.1-59593-271-2http://nrs.harvard.edu/urn-3:HUL.InstRepos:26563633Decision-theoretic optimization is becoming a popular tool in the user interface community, but creating accurate cost (or utility) functions has become a bottleneck --- in most cases the numerous parameters of these functions are chosen manually, which is a tedious and error-prone process. This paper describes ARNAULD, a general interactive tool for eliciting user preferences concerning concrete outcomes and using this feedback to automatically learn a factored cost function. We empirically evaluate our machine learning algorithm and two automatic query generation approaches and report on an informal user study.en-USConference Paper2016-04-1810.1145/1095034.1095063
