Decision Tradeoff Using Example-Critiquing and Constraint Programming

Pearl Pu, Boi Faltings
2004 Constraints  
We show how a preference model based on soft constraints is well-suited for supporting these strategies.  ...  Such a framework provides an agile preference model particularly powerful for preference revision during tradeoff analysis.  ...  In traditional decision theory, a preference elicitation process poses queries to the user.  ...

When data management systems meet approximate hardware

Bingsheng He
2014 Proceedings of the VLDB Endowment

Privacy-safe network trace sharing via secure queries

Jelena Mirkovic
2008 Proceedings of the 1st ACM workshop on Network data anonymization - NDA '08  
In this paradigm, a data owner publishes a query language and an online portal, allowing researchers to submit sets of queries to be run on data.  ...  We claim that a better balance in the utility/privacy tradeoff, inherent to network data sharing, can be achieved via a new paradigm we propose: secure queries.  ...  Solutions to privacy/utility tradeoff can broadly be classified as sanitized databases or statistical databases.  ...
