English(EN) When Are Two SAE Latents the Same Feature?

新框架可实现跨语言模型的稀疏自编码器比较

研究人员开发了一个新框架,通过连接特征对应关系、字典差异和评估数据中的不确定性来比较稀疏自编码器(SAE)。该框架利用能量加权最优传输方案来定义和分解字典级别的差异到潜在贡献。它还表征了各种相似性度量之间的关系,并提供了一种联合渐近推断和同步置信区间的方法,该方法已在四个语言模型上进行了测试,以识别差异和上下文相关的变化。 AI

影响 提供了一种新颖的分析工具,用于理解和比较大型语言模型内部的表示。

    两个 SAE 潜在特征何时相同?

    Comparing sparse autoencoders (SAEs) requires connecting feature correspondence, differences between whole dictionaries, and uncertainty from finite evaluation data. We develop a framework that connects these tasks through an energy-weighted optimal-transport plan under a specifi…
