大语言模型用「共享几何」表示和变换概念

手把手的具体实现讲解


一、场景设定(让所有抽象概念落地)

假设我们要复现论文的核心实验。我们选:

  • 概念词表W = ["apple", "chair", "freedom", "justice", "carpet", "hope", ...](论文用了 40 个词)
  • 上下文模板:6 种
    • τ₀(中性):"Thinking of the following concept: {w}."
    • τ₁(类别):"Thinking of the conceptual category of {w}."
    • τ₂(感知):"Thinking of the sensory and perceptual properties of {w}."
    • τ₃(场景):"Thinking of a typical situation involving {w}."<
