Tasks such as counting, filtering, or spotting trends need exact access to every value. The authors trace this failure to attention dispersion: as inputs grow, Softmax spreads attention over many similar numeric tokens… 2. **[PRA-RAG: Provably Robust Aggregation in Retrieval-Augmented Generation against Retrieval Corruption](https://md.research.elamur.ai/free/en/papers/tan-2026-pra-rag-provably-robust-aggregation/)** *(2026)* Retrieval-Augmented Generation can be hijacked when attackers plant crafted passages in the knowledge base so that the LLM returns an answer they chose. ## All works 3 works of theirs in our library, the most cited first; 2 with a page here, the others link their original until we summarise them. 1. **[SepSeq: A Training-Free Framework for Long Numerical Sequence Processing in LLMs](https://md.research.elamur.ai/free/en/papers/sun-2026-sepseq-training-free-framework-long/) [Findings of the Association for Computational Linguistics](https://md.research.elamur.ai/free/en/venues/findings/)**Jie Sun, Yu Liu, Lu Han, et al.*2026 · 1 citation* 2. **[PRA-RAG: Provably Robust Aggregation in Retrieval-Augmented Generation against Retrieval Corruption](https://md.research.elamur.ai/free/en/papers/tan-2026-pra-rag-provably-robust-aggregation/) [Findings of the Association for Computational Linguistics](https://md.research.elamur.ai/free/en/venues/findings/)**Xue Tan, Yi Zheng, Chang Huo, et al.*2026* 3. **[Two Streams, One Sarcasm: Orthogonal Expert Tuning for Holistic Multimodal Sarcasm Understanding ↗](https://aclanthology.org/2026.acl-long.319/) Proceedings of the 64th Annual Meeting of the Association for Computational Linguistics (Volume 1: Long Papers) · no summary yet**Diandian Guo et al.*2026* ## Co-authors here 8 co-authors with a page, the most papers together first. - [Jie Sun](https://md.research.elamur.ai/free/en/authors/jie-sun/) - [Jun Zhou](https://md.research.elamur.ai/free/en/authors/jun-zhou/) - [Pengfei Liu](https://md.research.elamur.ai/free/en/authors/pengfei-liu/) - [Xiang Wang](https://md.research.elamur.ai/free/en/authors/xiang-wang/) - [Xiaoyan Sun](https://md.research.elamur.ai/free/en/authors/xiaoyan-sun/) - [Xingyu Lu](https://md.research.elamur.ai/free/en/authors/xingyu-lu/) - [Yang Xiao](https://md.research.elamur.ai/free/en/authors/yang-xiao/) - [Yi Zheng](https://md.research.elamur.ai/free/en/authors/yi-zheng/) ## 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/) ×2: [Findings of the Association for Computational Linguistics 2026](https://md.research.elamur.ai/free/en/venues/findings/2026/) ×2 - Proceedings of the 64th Annual Meeting of the Association for Computational Linguistics (Volume 1: Long Papers) ## Cited by Papers of our library cite their works 1 time (of the 149,439 papers whose bibliographies we read).
