概要

この論文は、大規模言語モデル（LLM）の表現空間において、一意の人間の性質、価値観、そして信念のセットとして定義されたペルソナがどのようにそしてどこでエンコードされるかについての研究を提示します。様々な次元縮小およびパターン認識方法を使用して、まず、これらの表現の符号化における最大の差を示すモデル階層を識別する。次に、選択されたレイヤー内のアクティベーションを分析し、共有および独立した埋め込みスペースを含む特定のペルソナが他のペルソナに対してどのようにエンコードされるかを調べます。いくつかの事前訓練されたデコーダ専用LLMで分析されたペルソナは、デコーダ階層の最後の3分の1内でのみ表現空間に大きな違いを示すことがわかりました。道徳的虚無主義や公理主義などの特定の倫理的観点では、重複する活性化が観察され、多義性が現れたことを示唆している。一方、保守主義や自由主義などの政治理念は、より区別される分野で表現されることが示されています。これらの結果は、LLMが内部的に情報をどのように表現するかを理解し、LLM出力における特定の人間の特性の変調を改善するための将来の努力に情報を提供する可能性があります。注意：この論文には潜在的に不快なサンプル文が含まれています。
