Overview
Self-attention mechanisms in Transformers typically incur costs that increase with context length, leading to higher demands for storage, compute, and energy. A new method using symmetry-aware Taylor approximation aims to maintain constant cost per token for self-attention, potentially alleviating these resource demands.

Based on 5 sampled comments from this thread. Analyzed 2026-02-04.
- Concern: The pursuit of linear time attention is fundamentally flawed, as it contradicts established principles of attention mechanisms, suggesting a dead-end in research efforts.
- Concern: There are significant concerns that approximating attention may diminish its effectiveness, particularly in scenarios requiring sharp focus on critical information.
- Concern: The paper's approach may not adequately address the region of convergence, raising doubts about its mathematical soundness and practical applicability.
