  • Data Contamination or Genuine Generalization? Disentangling LLM Performance on Benchmarks
    Authors: Yui Ishikawa
    Resource Type: Article
    Disciplines: Computer Science | Subjects: Artificial Intelligence
    Publication ID: v2n2a03
    Abstract: Large language models (LLMs) achieve high benchmark performance, but whether this stems from genuine generalization or data contamination remains unclear. This paper proposes a three-tier framework to disentangle these effects, combining n-gram...
