RESA aims to recover context lost in sparse attention
The September 29, 2026 entry describes RESA, a residual-estimation proposal for recovering context missed when sparse attention selects only part of the KV cache. The post claims the technique adds no computational cost.
The September 29, 2026 entry presents the RESA paper. Its proposal uses residual estimation to recover context that may be missed when sparse attention selects only part of the KV cache. The post claims the technique adds no computational cost.
To assess that claim, consult the original paper and post and check how they define cost, which methods and conditions they compare, and what results they report. The available summary gives no benchmarks or experimental details, so it cannot establish on its own that the technique has no additional cost in every setting.
