Studia Logica: An International Journal for Symbolic Logic, Vol. 48, No. 4 (1989), pp. 449-459 (11 pages) We prove that the intuitionistic sentential calculus is Ł-decidable (decidable in the sense of ...
Inductive logic programming (ILP) and machine learning together represent a powerful synthesis of symbolic reasoning and statistical inference. ILP focuses on deriving interpretable logic rules from ...
