A Unified Deep Model of Learning from both Data and Queries for Cardinality Estimation [PDF]
Proceedings of the 2021 International Conference on Management of Data, 2021 Cardinality estimation is a fundamental problem in database systems. To capture the rich joint data distributions of a relational table, most of the existing work either uses data as unsupervised information or uses query workload as supervised information.

Reasoning with Finite Sets and Cardinality Constraints in SMT [PDF]
Logical Methods in Computer Science, 2018 We consider the problem of deciding the satisfiability of quantifier-free formulas in the theory of finite sets with cardinality constraints. Sets are a common high-level data structure used in programming; thus, such a theory is useful for modeling ...

Reconsidering the use of rankings in the valuation of health states: a model for estimating cardinal values from ordinal data [PDF]
Population Health Metrics, 2003 BACKGROUND: In survey studies on health-state valuations, ordinal ranking exercises often are used as precursors to other elicitation methods such as the time trade-off (TTO) or standard gamble, but the ranking data have not been used in deriving cardinal valuations.

A unifying model for representing time-varying graphs [PDF]
International Conference on Data Science and Advanced Analytics, 2014 Graph-based models form a fundamental aspect of data representation in Data Sciences and play a key role in modeling complex networked systems. In particular, recently there is an ever-increasing interest in modeling dynamic complex networks, i.e ...

Estimating population cardinal health state valuation models from individual ordinal (rank) health state preference data [PDF]
, 2004 Ranking exercises have routinely been used as warm-up exercises within health state valuation surveys. Very little use has been made of the information obtained in this process. Instead, research has focussed upon the analysis of health state valuation data obtained using the visual analogue scale, standard gamble and time trade off methods.

SetVAE: Learning Hierarchical Composition for Generative Modeling of Set-Structured Data [PDF]
Computer Vision and Pattern Recognition, 2021 Generative modeling of set-structured data, such as point clouds, requires reasoning over local and global structures at various scales. However, adopting multi-scale frameworks for ordinary sequential data to a set-structured data is nontrivial as it ...
