English(EN) Quantifying the Agreement Between Data-Influence and Data-Similarity to Understand LLM Behavior

新研究量化了LLM中数据影响与数据相似性之间的一致性

研究人员量化了用于将LLM输出追溯到其训练数据的数据相似性与数据影响度量之间的一致性。他们的发现表明,这两种度量之间存在显著的重叠,数据影响度量为数据相似性确定的顶级文档分配了更一致的排名。在对OLMo2-1B、Qwen3-1.7B、LlaMa3.2-1B、Gemma3-1B和GPT2等模型的实验中都观察到了这种不对称性。该研究建议利用这种不对称性,通过使用数据影响度量来改进数据相似性结果,从而实现更好的成本-准确性权衡。 AI

影响 提供了一种理解LLM行为的新方法,并可能优化训练数据分析。

    量化数据影响与数据相似性之间的一致性以理解大语言模型行为

    One way to understand LLM behavior is to trace its output back to the training data. Two types of measures are commonly used for output tracing: data-similarity and data-influence. The former is cheaper while the latter is believed to be more accurate. Even though many works have…
