English(EN) Output Dilution: Redundant but Fragile Representations in MoE Models

MoE 模型显示出脆弱的道德编码,尽管存在冗余表示

一篇新的 arXiv 论文,题为“输出稀释:MoE 模型中冗余但脆弱的表示”,研究了道德内容在专家混合(MoE)模型中的编码。研究人员发现,尽管像 OLMoE-1B-7B 这样的 MoE 模型可以高精度地编码道德效价,但与密集模型相比,这些表示对噪声的脆弱性显著更高。这种脆弱性归因于“输出稀释”,即跨专家平均会降低信号强度,使其容易受到扰动。 AI

影响 揭示了 MoE 模型中潜在的架构漏洞,这可能会影响它们在实际应用中的鲁棒性。

    arXiv:2608.25231v1 Announce Type: cross Abstract: Mixture-of-Experts (MoE) models appear to encode moral content as robustly as dense models, yet prove far more fragile in their encoding. In OLMoE-1B-7B, linear probes recover moral valence from nearly every expert-layer combinati…
