研究揭示了 Transformer 和 SSM 在层重要性方面的根本差异

一篇新发表在 arXiv 上的研究论文通过分析层重要性,探讨了 Transformer 和状态空间模型(SSM)之间的差异。该研究引入了两个指标:“必要性”(necessity),衡量层对其现有贡献的依赖程度;以及“可塑性”(plasticity),量化层在微调过程中吸收新信息的能力。研究结果表明,在 Transformer 中,必要性和可塑性在深度上呈负相关;而在 Mamba 类 SSM 中,它们则一致。这种差异也预示了下游适应行为,Transformer 在更新集中在可塑层时表现出灾难性遗忘增加,而所评估的 SSM 则没有这种效应。 AI

影响 为理解主要 AI 模型架构之间的根本差异提供了见解,可能指导未来的模型开发和微调策略。

    层级重要性揭示了 Transformer 和状态空间模型什么?

    arXiv:2609.16537v1 Announce Type: cross Abstract: Transformers and state-space models (SSMs) are the two dominant families of sequence models, and a central open question is how far the analytical knowledge built for transformers transfers to SSMs. We address this through the len…
