SLAP: Stratified Loss-based Pruning for On-Policy Data-Efficient Instruction Tuning

arXiv:2605.23969v1 Announce Type: new Abstract: Instruction tuning has optimized the specialized capabilities of large language models (LLMs), but it often requires extensive datasets and prolonged training times. The challenge lies in developing specific capabilities by identifying useful data and efficiently fine-tuning. High-quality and diverse pruned data can help models achieve lossless performance at a lower cost. In this paper, we propose \textbf{SLAP}, a novel batch-aware data selection framework that evaluates the learnability of entire batch compositions rather than individual. SLAP

Why this matters
Why now

The proliferation of increasingly large language models necessitates more efficient tuning methods to manage computational costs and data burdens, making research like SLAP critically relevant.

Why it’s important

Reducing the data and computational resources required for instruction tuning expands access to advanced AI development and lowers the barrier for specialized LLM applications.

What changes

The ability to achieve 'lossless performance at a lower cost' with LLMs fundamentally shifts the economics and accessibility of advanced AI model customization and deployment.
