Incomplete Information: Structure, Inference, Complexity

Jouni Järvinen
2006 Studia Logica: An International Journal for Symbolic Logic  
With respect to indiscernibility relations dependency relations resembling functional dependencies in relational databases and implications in formal concept analysis may be defined.  ...  The idea is that in many situations our knowledge of objects is incomplete, and it can be viewed as being restricted by some indiscernibility relations.  ...  With respect to indiscernibility relations dependency relations resembling functional dependencies in relational databases and implications in formal concept analysis may be defined.  ...

Concept lattices and conceptual knowledge systems

Rudolf Wille
1992 Computers and Mathematics with Applications  
First, basics on concept lattices are explained startin8 from simple data contexts which consist of a binary relation between objects and attrlbutet indicating which object has which attribute.  ...  Abstracts"Concept Lattice" is the central notion of aFormal Concept Analysis," a new area of research which is ba~ed on a set-theoreticed model for concepts and conceptual hierarchies.  ...  The small concept lattice in Figure 12 indicates that there is a large number of functional dependencies in the many-valued context of Figure 7 .  ...

Supporting Software Variability by Reusing Generic Incomplete Models at the Requirements Specification Stage [chapter]

2004 Lecture Notes in Computer Science  
Selecting components that satisfy a given set of requirements is a key problem in software reuse, especially in reusing between different domains of functionality.  ...  In this paper, we define generic incomplete specifications, to introduce an explicit source of variability that allows reusing models across different domains, accommodating them to operate in multiple  ...  AE ½ Å Ì ½ Ì ½ (1) Our proposal in this paper is to organize the repository in a single lattice of generic components, using the Å Ì ½ relations.  ...

Concept analysis for product line requirements

Nan Niu, Steve Easterbrook
2009 Proceedings of the 8th ACM international conference on Aspect-oriented software development - AOSD '09  
We take advantage of both symmetric and asymmetric views of aspects, and perform formal concept analysis to examine the functional and quality requirements of an evolving product line.  ...  The resulting concept lattice provides a rich notion which allows remarkable insights into the modularity and interactions of requirements.  ...  We also thank John Mylopoulos and Krzysztof Czarnecki for careful comments on earlier drafts of this paper. Funding was provided by NSERC.  ...

Gravitational and Quantum Effects in Neuron Function

Such a density-matrix description can be viewed as a probability mixture of different wave-functions.  ...  But for a more precise equation in relation to the stress-energy tensor, we know that in a non-zero temperature, the wave-function is not enough to describe the physical reality.  ...  Penrose, in 2014 argued that some conscious features such as understanding are not algorithmic computable and this incompleteness relates to the incomplete laws of physics at the scale of the brain which  ...

Stationary-state electronic distribution in quantum dots

Karel Král, Petr Zdeněk

We wish to draw an attention to a non-gibbsian behavior of zero-dimensional semiconductor nanostructures, which appears to be manifested in experiments by an effect of incomplete depopulation from electronic  ...  In the present work the effect is interpreted with help of electron-LO-phonon interaction, which is supposed to play a role in these structures in the form of multiple-scattering of electron on the optical  ...  lattice of the nanostructure, making the environment, in which a charge-carrier moves, to be a system with non-conservative property from energy point of view.  ...

Towards declarative comparabilities: application to functional dependencies [article]

Lhouari Nourine and Jean Marc Petit and Simon Vilmin
2021 arXiv   pre-print
This function maps each pair of the attribute's domain to a truth value in a truth lattice. Then, we associate a lattice of comparabilities to every relation, comparing pairwise its tuples.  ...  Thus, we introduce a lattice-based declarative framework to cope with this issue. First, we assign a comparability function to each attribute of the relation scheme.  ...  It offers a new point of view on FDs in presence of incomplete information.  ...
