研究量化了大型语言模型中Transformer的浓度现象

一篇新的研究论文探讨了用于大型语言模型和基础模型中的Transformer的浓度现象。该研究聚焦于推理时的仅编码器Transformer,并使用均场连续方程在大token限制下描述其行为。研究人员证明,token分布会快速集中并在中等时间内保持亚稳态,其Wasserstein距离根据温度和推理时间进行缩放。研究结果表明,对于与实际有限深度模型相关的时标而言,token分布会集中到一个极限分布,尽管数值实验表明在有限温度和大推理时间下存在不同的终端阶段。 AI

影响 为Transformer模型的推理行为提供了理论见解,可能为未来的模型设计和优化提供信息。

    Quantifying Concentration Phenomena of Mean-Field Transformers in the Low-Temperature Regime

    arXiv:2605.10931v2 Announce Type: replace-cross Abstract: Transformers with self-attention modules as their core components have become an integral architecture in modern large language and foundation models. In this paper, we study the evolution of tokens in deep encoder-only tr…
