状态-预测分离假设:Transformer 用独立计算流分离状态存储与下一 token 预测
The State-Prediction Separation Hypothesis
AI 导读
研究者提出“状态-预测分离假设”,认为将 Transformer 中“预测下一 token”与“为未来预测存储状态”两种角色解耦可提升语言建模性能。他们设计了一种使用独立计算流的 Transformer 变体,并在多种规模下开展预训练实验,结果显示该设计在数据与计算效率上持续更优,下游任务平均比标准 Transformer 高 2-3 个百分点。

Abstract:Transformers use the same forward computation stream to both predict the next token and store useful state for future token predictions. We formulate the state-prediction separation hypothesis: disentangling the two roles yields better language modeling performance. We design a Transformer variant that uses separate computation streams to separate the two functions, and conduct pretraining experiments across various scales. Our experiments show that state-prediction separation consistently offers better data- and compute-efficiency, improving validation loss and outperforming standard Transformers by 2-3 percentage points on average on downstream tasks. We also conduct extensive empirical analysis that rules out potential confounders and demonstrates the fundamental difference in the gradients our design entails.
