AI总结:

针对现有指令学习忽略不同类别指令交互依赖的问题,本文研究指令交互依赖模式,提出基于线性规划的指令集优化方法和依赖引导的SFT课程学习方案,在多个基准上取得优于强基线的效果。

摘要:

随着各类指令数据集的出现,一个关键挑战是如何有效选择并整合这些指令以微调大语言模型(LLMs)。以往研究主要聚焦于筛选单条高质量指令,但这类工作忽略了不同类别指令间的联合交互与依赖关系,导致选择策略并非最优。此外,这些交互模式的本质在很大程度上仍未被探索,更不用说基于它们来优化指令集了。为填补这些空白,本文:(1)系统研究了不同类别指令间的交互与依赖模式;(2)采用基于线性规划的方法,结合交互模式优化指令集,并通过指令依赖分类引导的课程学习优化监督微调(SFT)的学习范式。在不同大语言模型上的实验结果表明,该方法在广泛采用的基准测试上的性能优于强基线模型。

英文摘要:

With the availability of various instruction datasets, a pivotal challenge is how to effectively select and integrate these instructions to fine-tune large language models (LLMs). Previous research mainly focuses on selecting individual high-quality instructions. However, these works overlooked the joint interactions and dependencies between different categories of instructions, leading to suboptimal selection strategies. Moreover, the nature of these interaction patterns remains largely unexplored, let alone optimize the instruction set with regard to them. To fill these gaps, in this paper, we: (1) systemically investigate interaction and dependency patterns between different categories of instructions, (2) manage to optimize the instruction set concerning the interaction patterns using a linear programming-based method, and optimize the learning schema of SFT using an instruction dependency taxonomy guided curriculum learning. Experimental results across different LLMs demonstrate improved performance over strong baselines on widely adopted benchmarks.
