This paper presents an experimental analysis of a method recently proposed for refining knowledge bases expressed in a first order logic language. The method consists in transforming a classification theory into a neural network, called First Order logic Neural Network (FONN), by replacing predicate semantic functions and logical connectives with continuous-valued derivable functions. In this way...
This paper proposes a method for refining numerical constants occurring in rules of a knowledge base expressed in a first order logic language. The method consists in tuning numerical parameters by performing error gradient descent. The knowledge base to be refined can be manually handcrafted or automatically acquired by a symbolic relational learner, able to deal with numerical features. The results...
