Sample text

It proposes a framework to mine minimal generators of (i) closed OR-clauses, (ii) closed AND-clauses, (iii) closed maximal min-DNF, and (iv) closed maximal min-CNF. It requires establishing a mapping from the space of minimal generators to the space of arbitrary Boolean expressions, so that we could study the desired Boolean expressions induced by {a, b, c}. Thus, BLOSOM might not provide the knowledge of Boolean expression that we wish to study. • A specific framework for a specific type of Boolean expressions is introduced.

Iv) Any expression obtained by applying steps (i), (ii) and (iii) finitely is a Boolean expression. Our objective is not to give a formal definition of a well formed Boolean expression induced by X, but to understand how a Boolean expression induced by X could be constructed using a step-by-step approach. There are some other nonfundamental operators in Boolean algebra. Some examples of non-fundamental operators are NAND, NOR, and XOR. Any Boolean expression could be expressed by the set of operators {¬, ∧, ∨}.

This chapter introduces conditional patterns in a database and proposes an algorithm to mine them. Thus, we could reveal more characteristics of a database using conditional patterns. Also, we have observed that conditional patterns store significant nuggets of knowledge about a database that are not immediately available from frequent itemsets and association rules. In Sect. 1, we have presented an application of conditional patterns in a database. In future also, we shall search for more applications of conditional patterns in a database.
