| Abstract(in English) | In the PAC-learning,or the query learning model,it has been an important open problem to decide whether the class of DNF or CNF formulas is learnable.Recently,it was pointed out that the problem of PAC-learning for these classes with membership queries can be reduced to that of query learning for the class of k-quasi Horn formulas with membership and equivalence queries.A k-quasi Horn formula is a CNF formula with each clause containing at most k positive literals.In this paper,a notion of F-Horn formulas,which is an extention of k-quasi formulas,is introduced,and,it is shown that under some condition,the class of orthogonal F-Horn formulas is learnable with membership,equivalence and subset queries. |
