  • TLDR:We introduce the Extender, a log-structured variant of the standard Transformer architecture. In a standard Transformer, each layer communicates with subsequent layers exclusively via the residual h, a superposition channel. The Extender adds a concatenation channel x: each layer ell emits both a residual update δ_ell which is added to h, and a much smaller extension ε_ell which is appended to x. While both the FFN and q see h, the attention kv projections take only x as input. As a result, the fully extended x contains the complete input for the kv projections of all layers, reducing the pers

  • 标题中文:The Extender:一种日志结构 Transformer
  • TLDR中文:我们提出 Extender,作为标准 Transformer 架构的一种日志结构变体。在标准 Transformer 中,每一层仅通过残差通道 h 与后续层通信,h 是一种叠加通道。Extender 增加了一条拼接通道 x:每一层 ℓ 同时输出一个被加到 h 上的残差更新 δ_ℓ,以及一个被追加到 x 上的、规模更小的扩展 ε_ℓ。FFN 和 q 都读取 h,但注意力的 kv 投影仅以 x 作为输入。因此,完全扩展后的 x 包含了所有层 kv 投影所需的完整输入,从而降低了逐层持久化……
