Fixing paper assignments

  1. Please select all papers that belong to the same person.
  2. Indicate below which author they should be assigned to.
Provide a valid ORCID iD here. This will be used to match future papers to this author.
Provide the name of the school or the university where the author has received or will receive their highest degree (e.g., Ph.D. institution for researchers, or current affiliation for students). This will be used to form the new author page ID, if needed.

“面向大语言模型提供自然语言指令,可生成预期输出,体现了其上下文学习能力。上下文学习的性能与上下文模板质量密切相关,现有的工作通常使用单一的选择算法进行模板构建,无法充分激发上下文学习能力。本文提出基于动态聚类与标签空间映射的上下文学习模板构建方法,动态选择相关示例,进一步提出聚类筛选方法,实现不同语义簇中示例多样化的选择。设计基于损失函数的排序选择方法,评估模板学习正确标签空间映射分布的能力,排序形成最终模板。在自然语言推理等任务中的实验结果表明,本文提出的方法使两个不同的大语言模型准确率最高分别提升3.2%和8.9%。”
