TL;DR该研究提出了通过 PPTOD 模型和新的对话多任务预训练策略来解决任务导向对话系统中存在的级联生成问题,取得了针对几个基准 TOD 任务的最新成果。
Abstract
pre-trained language models have been recently shown to benefit task-oriented
dialogue (TOD) systems. Despite their success, existing methods often formulate
this task as a cascaded generation problem which can lead to error accumulation
across different sub-tasks and greater data anno
