Mathematical derivation of Kimi Delta Attention mechanism
July 28, 2026
Kimi Delta Attention (KDA) utilizes a state update equation where the previous state is modified by a diagonal matrix of alpha coefficients to produce a new state. This linear attention variant maps keys to values via a state-space transition that optimizes memory-efficient sequence processing.
