CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishWe present a framework for theory refinement operators ful- filling properties that ensure the efficiency and effectiveness of the learning process. A refinement operator satisfying these requirements is de- fined ideal. Past results have demonstrated the impossibility of defining ideal operators in search spaces ordered by the logical implication or the θ-subsumption relationships. By assuming the object identity bias over a space defined by a clausal language ordered by logical implication, we obtain OI-implication, a novel ordering relationship, and show that ideal operators can be defined for the resulting search space.

| Abstract: | We present a framework for theory refinement operators ful- filling properties that ensure the efficiency and effectiveness of the learning process. A refinement operator satisfying these requirements is de- fined ideal. Past results have demonstrated the impossibility of defining ideal operators in search spaces ordered by the logical implication or the θ-subsumption relationships. By assuming the object identity bias over a space defined by a clausal language ordered by logical implication, we obtain OI-implication, a novel ordering relationship, and show that ideal operators can be defined for the resulting search space. |
