Characterizing functional dependencies in formal concept analysis with pattern structures
2014
Annals of Mathematics and Artificial Intelligence
Preserved Fulltext
Computing functional dependencies from a relation is an important database topic, with many applications in database management, reverse engineering and query optimization. ...
Here, we present an alternative avoiding such a data representation and show how to characterize functional dependencies using the formalism of pattern structures, an extension of classical FCA to handle ...
We discuss data transformation with FCA in Section 3.3. It is followed by our main contribution which consists in characterizing functional dependencies with pattern structures (Section 4). ...

This article aims at presenting recent advances in Formal Concept Analysis (2010)(2011)(2012)(2013)(2014)(2015), especially when the question is dealing with complex data (numbers, graphs, sequences, etc ...
To overcome this problem, we present a characterization of functional dependencies in terms of (partition) pattern structures that offers additional benefits for the computation of dependencies [4] . ...

We propose an extended reservoir computer that shows the functional differentiation of neurons. ...
To develop neuronal units to show specificity, depending on the input information, the internal dynamics should be controlled to produce contracting dynamics after expanding dynamics. ...
The emergence of functional differentiation in the brain depends not only on gene expressions but on self-organization with constraints. ...

The system dependence graph (SDG) is a data structure used in the imperative paradigm for different static analysis, and particularly, for program slicing. ...
Unfortunately, the SDG cannot be used in the functional paradigm due to important features that are not considered in this formalism (e.g., pattern matching, higher-order, composite expressions, etc.). ...
The set of all restrictions in a graph is denoted with D r , and it can be easily computed with function constraints that takes the initial node of a pattern and the set of repeated variables in the parameters ...

To do so, we build on a powerful set of techniques that originate in the computer science field of "shape matching." ...
We demonstrate how shape matching techniques can be applied to identify unknown structures and create highly-specialized ad hoc order parameters. ...
Therefore, such projections can lead to non-distinguishing patterns for structures with radial dependence. ...
