arXiv (cs.CL) (Research): check the dataset, evaluation setup, and adoption assumptions for R&D.
Not all training samples contribute equally to large language model fine-tuning. Selecting informative training samples can reduce the computational cost while preserving downstream performance. Many existing data selection methods rely on indirect heuristics, such as data quality, diversity or reasoning trace length. However, the effectiveness of these fixed criteria is task-dependent and difficult to generalize across diverse downstream tasks. Perplexity-based data selecti…
ゼロビズAX View — How Japanese companies can apply it
中堅企業が自社向けにLLMを微調整する際、全データを使わず厳選することでGPU費用を30～50%削減できる可能性。ただし実装には言語処理の専門知識が必要で、クラウドAIサービス（AWS SageMaker等）での採用待ちが現実的。社内データの品質スコアリングから始め、予算枠内での最適選別ルール構築を検討する価値あり。
