Abstract: Premise selection and ranking is a pressing problem for applications of automated reasoning to large formal theories and knowledge bases. Smart selection of premises has a significant impact on the efficiency of automated proof assistant systems in large theories. Despite this, machine-learning methods for this domain are underdeveloped. In this paper we propose a general learning algorithm to address the premise selection problem. Our approach consists of simultaneous training of multiple predictors that learn to rank a set of premises in order to estimate their expected usefulness when proving a new conjecture. The proposed algorithm efficiently constructs prediction functions and can take correlations among multiple tasks into account. The experiments demonstrate that the proposed method significantly outperforms algorithms previously applied to the task.
