Pseudocomplements of closure operators on posets
Some recent results provide su cient conditions for complete lattices of closure operators on complete lattices, ordered pointwise, to be pseudocomplemented. This paper gives resu...

Encoding Closure Operators into Neural Networks
Motivated by basic ideas from formal concept analysis, we propose two ways to directly encode closure operators on finite sets in a 3-layered feed forward neural network.
