Draft, Sketch, and Prove: Guiding Formal Theorem Provers with Informal Proofs

ICLR 2023top-5%

The formalization of existing mathematical proofs is a notoriously difficult process. Despite decades of research on automation and proof assistants, writing formal proofs remains arduous and only accessible to a few experts. While previous studies to automate formalization focused on powerful searc…

HyperTree Proof Search for Neural Theorem Proving

NeurIPS 2022accept

We propose an online training procedure for a transformer-based automated theorem prover. Our approach leverages a new search algorithm, HyperTree Proof Search (HTPS), that learns from previous proof searches through online training, allowing it to generalize to domains far from the training distrib…

Canonical Tensor Decomposition for Knowledge Base Completion

ICML 2018oral

The problem of Knowledge Base Completion can be framed as a 3rd-order binary tensor completion problem. In this light, the Canonical Tensor Decomposition (CP) seems like a natural solution; however, current implementations of CP on standard Knowledge Base Completion benchmarks are lagging behind the…
