It does this by expressing each update in SVD form (P, Λ, Q) and pruning unimportant singular values. The cost is slow convergence and heavy computation during training. HyperAdaLoRA addresses this. Instead of updating P, Λ and Q directly… 2. **[Not All Directions Matter: Towards Structured and Task-Aware Low-Rank Model Adaptation](https://md.research.elamur.ai/free/en/papers/xiao-2026-not-all-directions-matter-structured/)** *(2026 · 3 citations)* The paper argues that LoRA has two weaknesses. First, it spends its small rank budget equally on every low-rank direction, even though many directions carry noise; the authors call this semantic drift. Second, it tunes each layer in isolation, so updates in neighbouring layers can point in unrelated directions; they… ## All works 4 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. **[Rumor Detection on Social Media with Bi-Directional Graph Convolutional Networks ↗](https://doi.org/10.1609/aaai.v34i01.5393) Proceedings of the AAAI Conference on Artificial Intelligence · no summary yet**Tian Bian et al.*2020 · 811 citations* 2. **[Adversarial Sparse Transformer for Time Series Forecasting ↗](https://openalex.org/W3097294131) neural information processing systems · no summary yet**Sifan Wu et al.*2020 · 109 citations* 3. **[HyperAdaLoRA: Accelerating LoRA Rank Allocation During Training via Hypernetworks without Sacrificing Performance](https://md.research.elamur.ai/free/en/papers/zhang-2026-hyperadalora-accelerating-lora-rank-allocation/) [Findings of the Association for Computational Linguistics](https://md.research.elamur.ai/free/en/venues/findings/)**Hao Zhang, Zhenjia Li, Yifan Gao, et al.*2026 · 5 citations* 4. **[Not All Directions Matter: Towards Structured and Task-Aware Low-Rank Model Adaptation](https://md.research.elamur.ai/free/en/papers/xiao-2026-not-all-directions-matter-structured/) [Annual Meeting of the Association for Computational Linguistics (ACL)](https://md.research.elamur.ai/free/en/venues/acl/)**Xi Xiao, Chenrui Ma, Yunbei Zhang, et al.*2026 · 3 citations* ## Co-authors here 11 co-authors with a page, the most papers together first. - [Hao Xu](https://md.research.elamur.ai/free/en/authors/hao-xu/) ×2 - [Tianyang Wang](https://md.research.elamur.ai/free/en/authors/tianyang-wang/) ×2 - [Bo Huang](https://md.research.elamur.ai/free/en/authors/bo-huang/) - [Chen Liu](https://md.research.elamur.ai/free/en/authors/chen-liu/) - [Hao Zhang](https://md.research.elamur.ai/free/en/authors/hao-zhang/) - [Heng Zhang](https://md.research.elamur.ai/free/en/authors/heng-zhang/) - [Lin Zhao](https://md.research.elamur.ai/free/en/authors/lin-zhao/) - [Shuyang Zhang](https://md.research.elamur.ai/free/en/authors/shuyang-zhang/) - [Yanshu Li](https://md.research.elamur.ai/free/en/authors/yanshu-li/) - [Yifan Gao](https://md.research.elamur.ai/free/en/authors/yifan-gao/) - [Yuhang Wu](https://md.research.elamur.ai/free/en/authors/yuhang-wu/) ## Venues Where their works here were published, the most works first, with the editions of those that have a page. - [Annual Meeting of the Association for Computational Linguistics (ACL)](https://md.research.elamur.ai/free/en/venues/acl/): [ACL 2026](https://md.research.elamur.ai/free/en/venues/acl/2026/) - [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/) - Proceedings of the AAAI Conference on Artificial Intelligence - neural information processing systems ## Cited by Papers of our library cite their works 63 times (of the 149,439 papers whose bibliographies we read); [13 citing papers with a page here →](https://md.research.elamur.ai/free/en/authors/xi-xiao/cited-by/).
