Inverse Queries For Multidimensional Spaces
Thomas Bernecker, Tobias Emrich, Hans-Peter Kriegel +4
Traditional spatial queries return, for a given query object , all database objects that satisfy a given predicate, such as epsilon range and -nearest neighbors. This paper d…
A Novel Probabilistic Pruning Approach to Speed Up Similarity Queries in Uncertain Databases
Thomas Bernecker, Tobias Emrich, Hans-Peter Kriegel +3
In this paper, we propose a novel, effective and efficient probabilistic pruning criterion for probabilistic similarity queries on uncertain data. Our approach supports a general u…
Probabilistic Frequent Pattern Growth for Itemset Mining in Uncertain Databases (Technical Report)
Thomas Bernecker, Hans-Peter Kriegel, Matthias Renz +2
Frequent itemset mining in uncertain transaction databases semantically and computationally differs from traditional techniques applied on standard (certain) transaction databases.…
Scalable Probabilistic Similarity Ranking in Uncertain Databases (Technical Report)
Thomas Bernecker, Hans-Peter Kriegel, Nikos Mamoulis +2
This paper introduces a scalable approach for probabilistic top-k similarity ranking on uncertain vector data. Each uncertain object is represented by a set of vector instances tha…
