Beyond Layer Importance in Layer-wise Sparsity: An Inter-Layer Perturbation-Absorption Perspective
arXiv:2606.15161v1 Announce Type: new Abstract: The considerable layer-wise redundancy in large language models (LLMs) has established non-uniform sparsity allocation across layers as the standard pruning approach for efficient compression. Existing layer-wise allocation methods that estimate allocation strategy from local signals such as activation outliers or weight spectra mainly derive from local layer importance, whereas the final post-pruning performance is also influenced by the network's subsequent compensatory capacity. In this paper, we directly characterize this property through con
The increasing scale and computational demands of large language models are driving a critical need for more efficient compression techniques, making advancements in sparsity allocation highly relevant.
Improving the efficiency of LLMs through better sparsity allocation directly impacts the cost and accessibility of advanced AI, influencing who can develop and deploy cutting-edge models.
This research introduces a new perspective on layer-wise sparsity, moving beyond local importance to consider inter-layer perturbation-absorption, potentially leading to more effective and performant model compression.
