R-Select: A Robust Multi-Metric Data Selection Approach for Fine-Tuning Large Language Models

R-Select, a robust and scalable framework that optimizes data selection with 30 distinct quality metrics, introduces a novel hierarchical optimization strategy that consistently outperforms both heuristic baselines and model-based methods, offering a robust solution for high-quality data curation.

R-Select: A Robust Multi-Metric Data Selection Approach for Fine-Tuning Large Language Models

The transition from architecture-centric scaling to data-centric refinement has established high-quality data as a critical determinant of Large Language Model performance, particularly for complex reasoning and instruction following. However, effective data selection remains a persistent bottleneck: simple heuristic f...
