Extracting Minimal and Closed Monotone DNF Formulas
Abstract. In this paper, first we introduce minimal and closed monotone DNF formulas as extensions of maximal and closed itemsets. Next, by incorporating the algorithm dnf cover d...

Extraction of Coverings as Monotone DNF Formulas
Abstract. In this paper, we extend monotone monomials as large itemsets in association rule mining to monotone DNF formulas. First, we introduce not only the minimum support but al...

Complexity of DNF and Isomorphism of Monotone Formulas
We investigate the complexity of finding prime implicants and minimal equivalent DNFs for Boolean formulas, and of testing equivalence and isomorphism of monotone formulas. For DN...

New Measure for Shape Elongation
Shape elongation is one of the basic shape descriptors that has a very clear intuitive meaning. That is reason for its applicability in many shape classification tasks. In this pap...
