Incremental Construction of Complex Aggregates: Counting over a Secondary Table.
Clément Charnay, Nicolas Lachiche, Agnès Braud · 2013
In this paper, we discuss the integration of complex aggregates in the construction of logical decision trees. We review the use of complex aggregates in TILDE, which is based on an exhaustive search in the complex aggregate space. As opposed to such a combinatorial search, we introduce a hill-climbing approach to build complex aggregates incrementally.
