研究发现,Transformer中的大规模激活遵循可预测的生命周期

研究人员详细介绍了Transformer模型中大规模激活的生命周期,这些激活是大规模残差流与注意力汇聚点相关联的坐标。研究表明,这些携带汇聚点的通道在训练早期就会稳定下来,并随着时间的推移整合到少数冗余的载体上。一个关键的发现是,权重衰减在因果关系上调节了这些激活的总体规模,移除权重衰减会允许持续增长,而保留权重衰减则会导致下降。该研究提出了一个平衡模型,其中AdamW预处理的增长与权重衰减相对抗,影响峰值激活的时间和幅度。 AI

影响 提供了对Transformer训练动态的更深入理解,可能为未来的模型优化和架构设计提供信息。
