Contextual Compression Encoding for Large Language Models: A Novel Framework for Multi-Layered Parameter Space Pruning
- 按上下文动态重组参数分布,分阶段压缩冗余参数组。
- 中层网络压缩率更高,文本生成与分类任务精度几乎不变。
- 适合资源受限环境部署,无需重训练且能耗与延迟明显下降。
随着模型规模持续扩大,上下文感知的压缩技术日益受到关注,以应对计算瓶颈。本文提出一种结构化编码方法,可选择性剔除冗余参数组,同时保持多层表征一致性。上下文压缩编码(CCE)引入多阶段编码机制,动态重构参数分布,显著降低内存占用和计算复杂度。实验表明,经CCE压缩的模型在文本生成与分类任务中保持语言表达力与连贯性,准确率稳定。层分析显示,中间层压缩率更高,自注意力与前馈变换存在可重组的冗余。相比传统量化与剪枝方法,CCE在效率与模型保留间取得更优平衡,实现能耗与推理延迟下降,且无需大量重训练。在资源受限场景下,内存减少使部署更具可扩展性。内部行为分析还发现,压缩模型激活分布稳定,能动态适应输入变化,验证了结构化压缩对大规模架构优化的有效性。
原文摘要 · Abstract (English)
Context-aware compression techniques have gained increasing attention as model sizes continue to grow, introducing computational bottlenecks that hinder efficient deployment. A structured encoding approach was proposed to selectively eliminate redundant parameter groups while ensuring that representational fidelity was preserved across multiple layers. Contextual Compression Encoding (CCE) introduced a multi-stage encoding mechanism that dynamically restructured parameter distributions, allowing for significant reductions in memory footprint and computational complexity. Experimental evaluations demonstrated that models compressed through CCE retained linguistic expressivity and coherence, maintaining accuracy across a range of text generation and classification tasks. Layer-wise analysis revealed that middle-network layers exhibited higher compression ratios, aligning with the observation that self-attention and feed-forward transformations contained redundancies that could be reorganized without impairing functional capacity. Comparisons against conventional quantization and pruning methods confirmed that CCE provided a more balanced trade-off between efficiency and model retention, achieving reductions in energy consumption and inference latency without requiring extensive retraining. Computational efficiency improvements were particularly evident in deployment scenarios involving resource-constrained environments, where reductions in memory usage enabled more scalable implementations. Further analyses of internal network behavior showed that compressed models exhibited stable activation distributions and adapted dynamically to input variations, reinforcing the viability of structured compression strategies for optimizing large-scale architectures.
