循环Transformer:有限步失败分析

研究人员分析了循环Transformer中一种现象,即迭代推理可能导致对参考答案的支持减少,从而导致有限步失败。当局部有利的更新方向导致有害的完全更新时,就会发生这种情况。该研究提出了一种方法,使用路径曲率分解和局部二次模型来表征这种进展损失,该模型可以预测增益和有用的步长。在数学和常识任务上的实验表明,采取所提出的位移的固定四分之一步长可以在相当大比例的失败中为参考效用带来积极的收益。 AI

影响 识别出迭代Transformer模型中的一种特定失败机制,有可能提高复杂任务的训练和性能。

    方向正确,步子错了:循环 Transformer 有限步失败的几何分析

    arXiv:2609.16665v1 Announce Type: cross Abstract: Looped Transformers offer a parameter-efficient route to test-time scaling by reusing shared layers for iterative latent reasoning. However, additional iterations can reduce support for a reference answer, leaving unclear whether …
