[HTML][HTML] Using congruence relations to extract knowledge from concept lattices

JF Viaud, K Bertet, R Missaoui, C Demko - Discrete Applied Mathematics, 2018 - Elsevier
It is well-known inside the Formal Concept Analysis (FCA) community that a concept lattice
could have an exponential size with respect to the input data. Hence, the size of concept …

The reverse doubling construction

JF Viaud, K Bertet, C Demko… - 2015 7th International …, 2015 - ieeexplore.ieee.org
It is well known inside the Formal Concept Analysis (FCA) community that a concept lattice
could have an exponential size in the data. Hence, the size of concept lattices is a critical …

Subdirect decomposition of contexts into subdirectly irreducible factors

JF Viaud, K Bertet, C Demko, R Missaoui - International Conference on …, 2015 - hal.science
The size of a concept lattice may increase exponentially with the size of the context. When
the number of nodes is too large, it becomes very difficult to generate and study such a …

[PDF][PDF] On infinite uniquely partitionable graphs and graph properties of finite character

J Bucko, P Mihók - Discussiones Mathematicae Graph Theory, 2009 - bibliotekanauki.pl
A graph property is any nonempty isomorphism-closed class of simple (finite or infinite)
graphs. A graph property is of finite character if a graph G has a property if and only if every …

Cadre général pour la recherche d'information et l'extraction de connaissances par l'exploration de treillis

JF Viaud - 2017 - theses.hal.science
Au cours des deux dernières décennies, nous avons été littéralement submergés par les
données. Nous recevons, rapidement, un flux colossal de données hétérogènes. Les …

Lattice decompositions through methods using congruence relations

JF Viaud, K Bertet, C Demko, R Missaoui - 2016 - hal.science
It is well known by analysts that a concept lattice has an exponential size in the data. Thus,
as soon as he works with real data, the size of the concept lattice is a fundamental problem …
