Decomposition of contexts into independent subcontexts based on thresholds
Roberto G. Aragón, Jesús Medina, Eloísa Ramírez-Poussa
The process of decomposing databases into smaller datasets, with the objective of extrapolating the information obtained in the smaller ones to the original database, represents a…
Independent subcontexts and blocks of concept lattices. Definitions and relationships to decompose fuzzy contexts
Roberto G. Aragón, Jesús Medina, Eloísa Ramírez-Poussa
The decomposition of datasets is a useful mechanism in the processing of large datasets and it is required in many cases. In formal concept analysis (FCA), the dataset is interpret…
Factorizing formal contexts from closures of necessity operators
Roberto G. Aragón, Jesús Medina, Eloísa Ramírez-Poussa
Factorizing datasets is an interesting process in a multitude of approaches, but many times it is not possible or efficient the computation of a factorization of the dataset. A met…
Impact of local congruences in variable selection from datasets
Roberto G. Aragón, Jesús Medina, Eloísa Ramírez-Poussa
Formal concept analysis (FCA) is a useful mathematical tool for obtaining information from relational datasets. One of the most interesting research goals in FCA is the selection o…
Reducing concept lattices by means of a weaker notion of congruence
Roberto G. Aragón, Jesús Medina, Eloísa Ramírez-Poussa
Attribute and size reductions are key issues in formal concept analysis. In this paper, we consider a special kind of equivalence relation to reduce concept lattices, which will be…
Decision support system for photovoltaic fault detection avoiding meteorological conditions
Roberto G. Aragón, M. Eugenia Cornejo, Jesús Medina +2
A fundamental issue about installation of photovoltaic solar power stations is the optimization of the energy generation and the fault detection, for which different techniques and…
