新方法利用 FFN 曲率恢复隐藏的 Transformer 结构

研究人员开发了一种新颖的方法,通过检查其曲率来对 Transformer 前馈网络 (FFN) 进行密码分析。该技术利用二阶泄露通道,特别是投影输入 Hessian,来揭示 FFN 内部隐藏的结构信息。即使在无法直接访问模型参数或梯度的情况下,该方法也能高精度地恢复隐藏的 FFN 方向。然后,这种结构恢复可用于创建能够精确模仿原始模型性能的高保真替代模型。 AI

影响 这项研究可能通过揭示隐藏的结构属性,为理解和潜在地保护 Transformer 模型带来新方法。

    平滑Transformer前馈网络的曲率密码分析

    arXiv:2608.28843v1 Announce Type: cross Abstract: We show that smooth two-layer feed-forward networks (FFNs) expose an additional structural model extraction channel under a chosen-input raw-output oracle at the FFN branch; consider transformer FFN branches with GELU or SiLU acti…
