One Shot vs. Iterative: Rethinking Pruning Strategies for Model Compression

arXiv:2508.13836v2 Announce Type: replace Abstract: Pruning is a core technique for compressing neural networks to improve computational efficiency. This process is typically approached in two ways: one-shot pruning, which involves a single pass of training and pruning, and iterative pruning, where pruning is performed over multiple cycles for potentially finer network refinement. Although iterative pruning has historically seen broader adoption, this preference is often assumed rather than rigorously tested. Our study presents one of the first systematic and comprehensive comparisons of these

Why this matters
Why now

The continuous drive for more efficient AI models, especially with increasing model sizes, makes optimizing compression techniques a critical and timely research area.

Why it’s important

Improving neural network pruning strategies offers a significant pathway to reduce computational overhead, enabling wider deployment of advanced AI models in resource-constrained environments.

What changes

Traditional assumptions about the superiority of iterative pruning are being re-evaluated, potentially streamlining model compression workflows and accelerating AI development cycles.
