A Method for Solving Quasi-Identifiers of Single Structured Relational Data
IEEE Access, 2021 Quasi-identifier is a set of attributes used to identify the specific entity in structured data, which can provide an inference path for query attacks.

Elaboration on functional dependencies: functional dependencies are dead, long live functional dependencies! [PDF]
ACM SIGPLAN Notices, 2017 Functional dependencies are a popular extension to Haskell's type-class system because they provide fine-grained control over type inference, resolve ambiguities and even enable type-level computations. Unfortunately, several aspects of Haskell's functional dependencies are ill-understood.

An Efficient and Scalable Algorithm to Mine Functional Dependencies from Distributed Big Data
Sensors, 2022 A crucial step in improving data quality is to discover semantic relationships between data. Functional dependencies are rules that describe semantic relationships between data in relational databases and have been applied to improve data quality ...

Dependent Functional Data [PDF]
ISRN Probability and Statistics, 2012 This paper reviews recent research on dependent functional data. After providing an introduction to functional data analysis, we focus on two types of dependent functional data structures: time series of curves and spatially distributed curves. We review statistical models, inferential methodology, and possible extensions.

Fuzzy Implication and Functional Dependency on Formal Context
Jurnal Matematika Integratif, 2020 Fuzzy formal concept analysis(FFCA) is a development of formal concept analysis(FCA) with the degree of relation between objects and attributes. Using FCA approach, we will investigate the condition logical implication for fuzzy functional dependency. We

Functional Dependence and Analytic Functions [PDF]
Canadian Mathematical Bulletin, 1979 AbstractWithout appealing to the Cauchy theorem or its corollaries, it is proved that the real and imaginary parts of a non-constant complex-valued analytic function of several complex variables are functionally independent. This unifies and generalizes some results sporadically treated in standard treatises on function theory.

Discovering Graph Functional Dependencies [PDF]
ACM Transactions on Database Systems, 2018 This article studies discovery of Graph Functional Dependencies (GFDs), a class of functional dependencies defined on graphs. We investigate the fixed-parameter tractability of three fundamental problems related to GFD discovery. We show that the implication and satisfiability problems are fixed-parameter tractable, but the validation problem is co-W[1]
