Abstract:

Deep learning has largely improved the performance of natural language understanding (NLU) systems. However, most deep learning models are black-box machinery, and lack explicit interpretation. In this talk, I will introduce our recent progress on neuro-symbolic reasoning for NLU , which combines different schools of AI, namely, symbolism and connectionism. Generally, we will design a neural system with symbolic structures for an NLU task, and apply reinforcement learning or its relaxation to perform weakly supervised reasoning in the downstream task. Our framework has been successfully applied to various tasks, including SQL command reasoning, syntactic structure reasoning, and logical reasoning.
