新定理解释了 Transformer 如何忘记提示词

研究人员开发了一个条件无毛定理,以解释自回归 Transformer 如何忘记其提示词。该定理指出,Transformer 的提示词影响会随着幂律衰减,已训练模型的遗忘速度比未训练模型更快。这种遗忘归因于注意力稀释和中继机制,其中提示词的直接影响随着上下文的增长而减弱,而续写 token 只能增加对数因子。研究表明,随着生成文本的增加,提示词的影响会消失,这意味着任何残留的提示词属性都必须由文本本身携带。 AI

影响 为理解和潜在地改进大型语言模型中的提示词保留提供了理论框架。

    Transformer 的条件无毛定理:语言模型如何忘记其提示

    Autoregressive transformers retain prompt influence via a power-law decay driven by attention dilution and relay mechanisms, with trained models forgetting faster than untrained ones.
