研究发现:大型语言模型中的Token表征流是非线性的

研究人员分析了神经网络中Token表征的流动,发现这种流动是非线性的,并且不遵循自身的密度。他们使用Pythia-160M和Pythia-410M上的离散Langevin模型,证明了二次漂移比线性映射更能准确地表示层转换。研究还揭示了流动的旋转分量很重要,它影响了诸如范数和浓度等Token属性在网络层之间的排名变化。 AI

影响 提供了对大型语言模型内部机制的更深入理解,可能为未来的模型架构和可解释性工作提供信息。

    Token表征的深度流是非线性的,并且不遵循其自身的密度下降

    arXiv:2608.29706v1 Announce Type: new Abstract: A token's representation is carried through the network layer by layer. The whole vocabulary carried together forms a flow. We fit this flow's equation of motion as a discrete Langevin model over corpus-mean trajectories of Pythia-1…
