Enumerating Minimal Hypotheses and Dualizing Monotone Boolean Functions on Lattices
نویسندگان
چکیده
Any monotone Boolean function on a lattice can be described by the set of its minimal 1 values. If a lattice is given as a concept lattice, this set can be represented by the set of minimal hypotheses of a classification context. Enumeration of minimal hypotheses in output polynomial time is shown to be impossible unless P = NP, which shows that dualization of monotone functions on lattices with quasipolynomial delay is hardly possible.

Exact Learning Boolean Function via the Monotone Theory
We study the learnability of boolean functions from membership and equivalence queries. We develop the Monotone Theory that proves 1) Any boolean function is learnable in polynomial time in its minimal DNF size, its minimal CNF size and the number of variables n. In particular, 2) Decision trees are learnable. Our algorithms are in the model of exact learning with membership queries and unrestr...
متن کاملSome results on $L$-complete lattices
The paper deals with special types of $L$-ordered sets, $L$-fuzzy complete lattices, and fuzzy directed complete posets.First, a theorem for constructing monotone maps is proved, a characterization for monotone maps on an $L$-fuzzy complete lattice is obtained, and it's proved that if $f$ is a monotone map on an $L$-fuzzy complete lattice $(P;e)$, then the least fixpoint of $f$ is meet of a spe...

We give a new algorithm counting monotone Boolean functions of n variables (or equivalently the elements of free distributive lattices of n generators). We computed the number of monotone functions of 8 variables which is 56 130 437 228 687 557 907 788. 2001 Elsevier Science B.V. All rights reserved.

متن کاملDualization in lattices given by ordered sets of irreducibles
Dualization of a monotone Boolean function on a finite lattice can be represented by transforming the set of its minimal 1 to the set of its maximal 0 values. In this paper we consider finite lattices given by ordered sets of their meet and join irreducibles (i.e., as a concept lattice of a formal context). We show that in this case dualization is equivalent to the enumeration of so-called mini...
