AI总结:

针对自然语言生成任务,提出一种基于序列补全的样本内课程学习方法,从生成最后几个词逐步扩展到生成完整序列,实验证明该方法泛化性强且显著优于强基线。

摘要:

课程学习通过从简单样本到困难样本训练机器学习模型,在多个领域展现出显著的改进。先前的工作要么设计规则,要么训练模型来评估难度,高度依赖特定任务的专业知识,且无法泛化。受“由易到难”直觉的启发,我们提出针对自然语言生成任务进行样本内课程学习。我们的学习策略从训练模型生成最后几个词开始,即进行序列补全,并逐步扩展到生成整个输出序列。综合实验表明,该方法能很好地泛化到不同任务,并在强基线上取得了显著改进。

英文摘要:

Curriculum learning has shown promising improvements in multiple domains by training machine learning models from easy samples to hard ones. Previous works which either design rules or train models for scoring the difficulty highly rely on task-specific expertise, and cannot generalize. Inspired by the "easy-to-hard" intuition, we propose to do in-sample curriculum learning for natural language generation tasks. Our learning strategy starts training the model to generate the last few words, i.e., do sequence completion, and gradually extends to generate the whole output sequence. Comprehensive experiments show that it generalizes well to different tasks and achieves significant improvements over strong baselines.
