Functional Dependencies Unleashed for Scalable Data Exchange [PDF]

International Conference on Statistical and Scientific Database Management, 2016
We address the problem of efficiently evaluating target functional dependencies (fds) in the Data Exchange (DE) process. Target fds naturally occur in many DE scenarios, including the ones in Life Sciences in which multiple source relations need to be ...

A comprehensive clinically informed map of dependencies in cancer cells and framework for target prioritization.

Cancer Cell
Genetic screens in cancer cell lines inform gene function and drug discovery. More comprehensive screen datasets with multi-omics data are needed to enhance opportunities to functionally map genetic vulnerabilities. Here, we construct a second-generation

Research on Increased Data Repair with Confidence Value Token

Jisuanji kexue yu tansuo, 2021
In the era of big data, data contain great value and become important strategic resource in today??s information society. However, a large number of inconsistent data occur during the process of data update and management, which causes unpredictable side

ABOUT FUNCTIONAL DIAGNOSTICS OF CARS WITH AN ELECTRIC POWER PLANT

International Journal of Advanced Studies, 2023
The article is devoted to the development of a method of functional diagnostics of cars with an electric power plant on stands with running drums. The necessity of carrying out functional diagnostics of cars with an electric power plant is analyzed.

Toward an Axiomatization of Strongly Possible Functional Dependencies

Vietnam Journal of Computer Science, 2021
In general, there are two main approaches to handle the missing data values problem in SQL tables. One is to ignore or remove any record with some missing data values.

Pattern functional dependencies for data cleaning

Proceedings of the VLDB Endowment, 2020
Patterns (or regex-based expressions) are widely used to constrain the format of a domain (or a column), e.g., a Year column should contain only four digits, and thus a value like "1980-" might be a typo.

A Statistical Perspective on Discovering Functional Dependencies in Noisy Data

SIGMOD Conference, 2020
We study the problem of discovering functional dependencies (FD) from a noisy data set. We adopt a statistical perspective and draw connections between FD discovery and structure learning in probabilistic graphical models.
