Activation- and Influence-Aware Ranks (AIR): Function-Preserving SVD Compression for LLMs

arXiv:2606.19993v1 Announce Type: new Abstract: We present Activation- and Influence-Aware Ranks (AIR), an SVD-based LLM compression framework that guides each weight matrix's low-rank approximation with a backward-signal influence metric. Starting from the activation-aware optimum of SVD-LLM(W), AIR runs a single closed-form alternating least squares (ALS) sweep that integrates influence element-wise under a monotone-descent guarantee. AIR is layer-local and composes orthogonally with end-to-end methods: alone it exceeds ACIP, and AIR+LoRA outperforms it further. AIR improves perplexity over

Why this matters
Why now

The continuous growth in LLM complexity and size necessitates more efficient compression techniques to enable broader deployment and reduce operational costs.

Why it’s important

This development offers a significant step towards practical and scalable deployment of large language models by substantially reducing their computational footprint without compromising performance.

What changes

LLMs can now be compressed more effectively using Activation- and Influence-Aware Ranks (AIR), leading to smaller models that are easier to run and integrate into various systems.
