arXiv:2507.06457v2 Announce Type: replace Abstract: Transformers face quadratic complexity and memory issues with long sequences, prompting the adoption of linear attention mechanisms using fixed-size hidden states. However, linear models often suffer from limited recall performance, leading to hybrid architectures that combine linear and full attention layers. Despite extensive hybrid architecture research, the choice of linear attention component has not been deeply explored. We systematically evaluate various linear attention models across generations - vector recurrences to advanced gating
The increasing demand for transformer models in processing longer sequences is driving current research into more efficient attention mechanisms.
Improved linear attention models could significantly enhance the scalability and efficiency of advanced AI models with long contexts, impacting various applications.
This research systematically evaluating hybrid linear attention means that future transformer architectures are likely to incorporate more optimized and efficient attention components.
