An Ensemble Approach for Automated Theorem Proving Based on Efficient Name Invariant Graph Neural Representations

IJCAI 2023poster

Using reinforcement learning for automated theorem proving has recently received much attention. Current approaches use representations of logical statements that often rely on the names used in these statements and, as a result, the models are generally not transferable from one domain to another.…

SYGMA: A System for Generalizable and Modular Question Answering Over Knowledge Bases

EMNLP 2022finding

Knowledge Base Question Answering (KBQA) involving complex reasoning is emerging as an important research direction. However, most KBQA systems struggle with generalizability, particularly on two dimensions: (a) across multiple knowledge bases, where existing KBQA approaches are typically tuned to a…
