Relational Learning over Dirty Data Using Data Constraints

Creator:

Lee, Ga Young

Abstract:

Real-world datasets are dirty and contain many errors. Examples of these issues are violations of integrity constraints, duplicates, and inconsistencies in representing data values and entities. Applying machine learning on dirty databases may lead to inaccurate results. Users have to spend a lot of time and effort repairing data errors...

AN ABSTRACT OF THE THESIS OF Ga Young Lee for the degree of
Collaborative Online Learning For Join Processing

Creator:

Xie, Mian

Abstract:

Relational binary operators, such as join, are arguably the most costly and frequently used operations in relational data systems. In many join algorithms, the majority of the process time is spent on scanning and attempting to join the parts of the relations that do not satisfy the join condition and...

Learning to Estimate Multi-Relation Aggregation Functions

Creator:

Jadhav, Rashmi Suresh

Abstract:

Multi-relation aggregation queries process the join operator before computing the aggregation function. This join is arguably the most costly operation since traditional join algorithms spend majority of their time trying to join the parts of the relations that do not generate any output tuples. This causes slow response times with...
