新的矩阵乘法方法确保了大型语言模型的前缀不变性

研究人员开发了低精度设置下快速矩阵乘法的新方法,特别解决了语言模型中的前缀不变性问题。标准的快速矩阵乘法技术会通过混合标记行来引入错误,从而损害前缀不变性——这是多项选择任务中准确计算似然得分的关键属性。研究表明,即使在看似准确的FP8实现中,OpenBookQA等基准测试中的模型答案也可能发生重大变化。为了解决这个问题,他们提出了经过认证的实现,保证与规定的整数运算符的比特级相等性,确保实现的选择不会改变得分的似然性,从而使决策纯粹基于成本。 AI

影响 确保大型语言模型中的计算选择不会改变模型输出,从而实现更高效、更可靠的推理。

    超越准确性:低精度快速矩阵乘法的无前缀不变实现

    arXiv:2609.39816v1 Announce Type: new Abstract: Fast matrix multiplication saves multiplications through exact cancellation, but rounding sums that mix token rows can leave contributions from later tokens in earlier language model outputs. This threatens prefix invariance, which …
