Sofian Maabout: Computation of Borders and Applications

14.00, Room 445 at PCRI Abstract Given a set of objects O and a boolean interest function q:2^O-> {true, false}, the border of 2^O is the set of extremal (minimal or maximal) subsets o of O s.t. q(o)=true. This concept is present in many contexts, e.g., maximal frequent itemsets, functional dependencies and partial matrialization of …
