Compute grows quadratically with length, and the KV-Cache can reach tens or hundreds of gigabytes at million-token scale. Sparse attention cuts computation but still keeps the whole cache. Linear attention is cheap but compresses context lossily and loses… 3. **[StateX: Enhancing RNN Recall via Post-training State Expansion](https://md.research.elamur.ai/free/en/papers/shen-2026-statex-enhancing-rnn-recall-post/)** *(2026 · 1 citation)* Recurrent language models such as linear attention and state-space models process long inputs at constant cost per token. ## Co-authors here 12 of 16 co-authors with a page, the most papers together first. - [Maosong Sun](https://md.research.elamur.ai/free/en/authors/maosong-sun/) ×2 - [Zhiyuan Liu](https://md.research.elamur.ai/free/en/authors/zhiyuan-liu/) ×2 - [Biyuan Lin](https://md.research.elamur.ai/free/en/authors/biyuan-lin/) - [Chenglei Si](https://md.research.elamur.ai/free/en/authors/chenglei-si/) - [Fanchao Qi](https://md.research.elamur.ai/free/en/authors/fanchao-qi/) - [MiniCPM Team](https://md.research.elamur.ai/free/en/authors/minicpm-team/) - [Qun Liu](https://md.research.elamur.ai/free/en/authors/qun-liu/) - [Xiaozhi Wang](https://md.research.elamur.ai/free/en/authors/xiaozhi-wang/) - [Xin Li](https://md.research.elamur.ai/free/en/authors/xin-li/) - [Xu Han](https://md.research.elamur.ai/free/en/authors/xu-han/) - [Yasheng Wang](https://md.research.elamur.ai/free/en/authors/yasheng-wang/) - [Yewei Fang](https://md.research.elamur.ai/free/en/authors/yewei-fang/) ## Venues Where their works here were published, the most works first, with the editions of those that have a page. - [Findings of the Association for Computational Linguistics](https://md.research.elamur.ai/free/en/venues/findings/): [Findings of the Association for Computational Linguistics 2026](https://md.research.elamur.ai/free/en/venues/findings/2026/) - [Transactions of the Association for Computational Linguistics (TACL)](https://md.research.elamur.ai/free/en/venues/tacl/): [Transactions of the Association for Computational Linguistics (TACL) 2023](https://md.research.elamur.ai/free/en/venues/tacl/2023/) ## Cited by Papers of our library cite their works 16 times (of the 149,439 papers whose bibliographies we read); [1 citing paper with a page here →](https://md.research.elamur.ai/free/en/authors/yingfa-chen/cited-by/).
