Pruning Deep Neural Networks via the Marchenko--Pastur Distribution

arXiv:2606.02608v1 Announce Type: new Abstract: We study a Marchenko--Pastur (MP) random-matrix approach to pruning deep neural networks with very small post-pruning fine-tuning budgets. The main practical contribution is accuracy retention under short calibration and fine-tuning schedules, rather than a long post-pruning reoptimization pipeline. The theory gives deterministic data-path certificates: if the removed component $R$ has small propagated logit effect $L_s \| R \psi_1(s) \|_\infty$, pruning decreases an elastic-net objective and preserves samples whose dense margin exceeds twice the

Why this matters
Why now

The increasing scale and computational cost of deep neural networks necessitate more efficient pruning methods to sustain advancement given current compute limitations.

Why it’s important

This research provides a more efficient method for pruning deep neural networks, significantly reducing the post-pruning fine-tuning budget, which directly impacts the speed and cost of AI model deployment and optimization.

What changes

The barrier to deploying smaller, more efficient AI models decreases, enabling faster iteration and broader application in resource-constrained environments.
