Cardinality and Identity

open access: yesJournal of Philosophical Logic, 2007
P.T. Geach has maintained (see, e.g., Geach (1967/1968)) that identity (as well as dissimilarity) is always relative to a general term. According to him, the notion of absolute identity has to be abandoned and replaced by a multiplicity of relative identity relations for which Leibniz’s Law – which says that if two objects are identical they have the ...

Cardinality Estimation in DBMS: A Comprehensive Benchmark Evaluation

Proceedings of the VLDB Endowment, 2021
Cardinality estimation (CardEst) plays a significant role in generating high-quality query plans for a query optimizer in DBMS. In the last decade, an increasing number of advanced CardEst methods (especially ML-based) have been proposed with ...

Flow-Loss: Learning Cardinality Estimates That Matter

Proceedings of the VLDB Endowment, 2021
Recently there has been significant interest in using machine learning to improve the accuracy of cardinality estimation. This work has focused on improving average estimation error, but not all estimates matter equally for downstream tasks like query ...
