新研究解决LLM量化鲁棒性和不确定性保持问题

两篇新研究论文探讨了在保持其性能和不确定性行为的同时,改进大型语言模型(LLMs)量化的方法。第一篇论文《Jacobian-guided Noise Injection for Quantization Robustness in Large Language Models》提出了一种训练策略,将高斯噪声注入预注意力logit中,其方差由雅可比矩阵弗罗贝尼乌斯范数确定,在图像和文本基准测试中显示出显著的收益。第二篇论文《Target-Aware Calibration Data Selection for Preserving Uncertainty in Quantized Language Models》引入了疑虑保留量化(DPQ),这是一种预量化技术,根据特定的部署目标选择校准数据,以在各种NLP任务中保持不确定性行为。 AI

影响 这些论文提供了新的技术,通过改进量化方法使LLMs更易于部署,从而可能带来更广泛的应用和更低的计算成本。

排序理由 两篇在arXiv上发表的学术论文,详细介绍了LLM量化的新颖方法。

    Jacobian-guided Noise Injection for Quantization Robustness in Large Language Models

    arXiv:2608.20988v1 Announce Type: cross Abstract: Quantization of Large Language Models (LLMs) is often hindered by the sensitivity of the self-attention mechanism to discretization errors. We identify the softmax operator as a bottleneck for quantization stability due to its sen…

    面向目标感知的校准数据选择以保留量化语言模型中的不确定性

    arXiv:2608.21019v1 Announce Type: cross Abstract: Quantization is widely used to deploy large language models, but its effect on uncertainty behavior, such as confidence, margins, and abstention, is rarely treated as a primary objective. We frame calibration-data selection for qu…
