Erase-then-Delta Attention: Decoupling Erase and Write Addresses in Delta-Rule Linear Attention
The authors propose Erase-then-Delta Attention (EDA), a memory update rule for recurrent models that decouples the address used to erase stale information from the address used to write new content. This approach addresses the limitation of delta-rule linear attention, which cannot actively remove outdated data stored at different locations before writing.
