SUMMARY:D4 seminar: Caio Corro (Sorbonne Université)
DESCRIPTION:Next D4 seminar will take place on January 24th at 2 pm in room C005. \nCaio Corro\, MCF at Sorbonne Université\, will give a talk entitled « Graph-based semantic parsing and compositional generalization ». \nAbstract:\n\nSemantic parsing aims to transform a natural language utterance into a structured representation that can be easily manipulated by a software (for example to query a database). As such\, it is a central task in human-computer interfaces. It has recently been observed that sequence-to-sequence models struggle on settings that require compositional generalization. \nIn this talk\, I will present our work on graph-based semantic parsing. We proposed two novel graph-based formulations of this problem. Both methods deliver novel state-of-art results on standard benchmarks that test for compositional generalization. Moreover\, I will explain how to build losses for learning when the alignment between concepts and words are not annotated in the data\, and briefly discuss theoretical limitation of token-separable losses that are commonly used in the literature (including the presented work).
