English(EN) Representational Capacity: Geometric Limits on Feature Representation in Transformer Language Models

新框架揭示了Transformer模型特征表示的几何限制

研究人员开发了一个新框架,用于理解Transformer语言模型中特征表示的几何限制。通过分析嵌入矩阵及其与近乎正交的偏差,他们识别出两类模型:偏差高、缺乏结构的模型,以及偏差低、保持结构的模型。这项工作提炼了对表示能力的理解,表明其对正交性约束呈指数级敏感,并且更大的模型优先考虑更严格的约束而非最大化原始能力。 AI

影响 为理解模型局限性和特征表示的潜在改进提供了理论视角。
