Regret-minimizing representative databases

Danupon Nanongkai, Atish Das Sarma, Ashwin Lall, Richard J. Lipton, Jun Xu
2010 Proceedings of the VLDB Endowment  
In particular, for any number k and any class of utility functions, the k-regret query outputs k tuples from the database and tries to minimize the maximum regret ratio.  ...  We propose the k-representative regret minimization query (k-regret) as an operation to support multi-criteria decision making.  ...  This query has been explored further in the domains of uncertain databases [21, 32] and continuous processing [19] .  ...

k-regret queries with nonlinear utilities

Taylor Kessler Faulkner, Will Brackenbury, Ashwin Lall
2015 Proceedings of the VLDB Endowment  
Prior work with k-regret queries assumes users' preferences to be modeled by linear utility functions.  ...  This approach combines benefits of the methods top-k and skyline; it controls the size of the output but does not require knowledge of users' preferences.  ...  [5] propose skyline frequency. This ranks points by counting the number of dimensions for which each point is in the skyline. Xia et al. [28] proposeskyline queries.  ...

Label Ranking mit probabilistischen Modellen

Weiwei Cheng, Mathematik Und Informatik, Hüllermeier, Eyke (Prof.)
Given a query instance (e.g., a customer) and a predefined set of candidate labels (e.g., AUDI, BMW, VW), a single label is required as a prediction in classification (e.g.  ...  The connection of these two fields has not been studied for label ranking before.  ...  In fact, our approach comes down to a very simple prediction procedure, in which labels are sorted according to their local frequency in the neighborhood of the query, and ties are broken by global frequencies  ...
