arXiv:2606.07690v1 Announce Type: new Abstract: Finetuning data selection requires balancing two competing goals: selecting examples that improve the downstream objective, and doing so without repeatedly finetuning models. Train-free selectors are scalable but rely on proxies such as embedding similarity or clustering, which may not match the target objective. Train-based selectors better reflect downstream utility through gradient signals, subset evaluation, or Shapley attribution, but require many costly train--evaluate iterations. We propose Hierarchical Active Region Pruning (HARP), an eff
The proliferation of increasingly complex large language models necessitates more efficient and effective finetuning data selection methods to manage computational costs and improve performance.
Efficient data selection techniques like HARP directly address the cost and computational bottlenecks of LLM training, impacting the accessibility and development speed of advanced AI systems.
The ability to finetune large language models more efficiently, without repeated costly training, changes the economics and timelines for deploying specialized AI applications.
