KeyFinder: An Efficient Minimal Keys Finding Algorithm For Relational Databases
In relational databases, it is essential to know all minimal keys since the concept of database normaliza- tion is based on keys and functional dependencies of a relation schema.

Anomalies Detection in Software by Conceptual Learning From Normal Executions
Could we detect anomalies during the run-time of a program by learning from the analysis of its previous traces for normally completed executions? In this paper we create a featured data set from program traces at run time, either during its regular life,

Propagating functional dependencies with conditions [PDF]
The dependency propagation problem is to determine, given a view defined on data sources and a set of dependencies on the sources, whether another dependency is guaranteed to hold on the view.

Finding the Transitive Closure of Functional Dependencies using Strategic Port Graph Rewriting [PDF]
We present a new approach to the logical design of relational databases, based on strategic port graph rewriting. We show how to model relational schemata as attributed port graphs and provide port graph rewriting rules to perform computations on ...

Discovering Approximate Functional Dependencies using Smoothed Mutual Information
We consider the task of discovering the top-K reliable approximate functional dependencies X -> Y from high dimensional data. While naively maximizing mutual information involving high dimensional entropies over empirical data is subject to false ...

Functional Dependence in Strategic Games (extended abstract) [PDF]
The paper studies properties of functional dependencies between strategies of players in Nash equilibria of multi-player strategic games. The main focus is on the properties of functional dependencies in the context of a fixed dependency graph for pay ...

Dependent Functional Data [PDF]
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.

Discovering Reliable Approximate Functional Dependencies [PDF]
Given a database and a target attribute of interest, how can we tell whether there exists a functional, or approximately functional dependence of the target on any set of other attributes in the data?

Functional Dependence and Analytic Functions [PDF]
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.
