Earlier style-transfer models mix sentiment and meaning in one dense hidden vector, so their outputs often drift off-topic. Xu et al. split the task between two cooperating components. 2. **[Be Careful about Poisoned Word Embeddings: Exploring the Vulnerability of the Embedding Layers in NLP Models](https://md.research.elamur.ai/free/en/papers/yang-2021-be-careful-about-poisoned-word/)** *(2021 · 134 citations)* Backdoor attacks make an NLP classifier behave normally on ordinary inputs but output an attacker-chosen class whenever a rare trigger word appears. ## All works 7 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. **[Unpaired Sentiment-to-Sentiment Translation: A Cycled Reinforcement Learning Approach](https://md.research.elamur.ai/free/en/papers/xu-2018-unpaired-sentiment-sentiment-translation-cycled/) [Annual Meeting of the Association for Computational Linguistics (ACL)](https://md.research.elamur.ai/free/en/venues/acl/)**Jingjing Xu, Xu Sun, Qi Zeng, et al.*2018 · 302 citations* 2. **[Be Careful about Poisoned Word Embeddings: Exploring the Vulnerability of the Embedding Layers in NLP Models](https://md.research.elamur.ai/free/en/papers/yang-2021-be-careful-about-poisoned-word/) [Conference of the North American Chapter of the Association for Computational Linguistics (NAACL)](https://md.research.elamur.ai/free/en/venues/naacl/)**Wenkai Yang, Lei Li, Zhiyuan Zhang, et al.*2021 · 134 citations* 3. **[Query and Output: Generating Words by Querying Distributed Word Representations for Paraphrase Generation ↗](https://aclanthology.org/N18-1018/) Proceedings of the 2018 Conference of the North American Chapter of the Association for Computational Linguistics: Human Language Technologies, Volume 1 (Long Papers) · no summary yet**Shuming Ma et al.*2018 · 79 citations* 4. **[A Hierarchical Reinforced Sequence Operation Method for Unsupervised Text Style Transfer ↗](https://aclanthology.org/P19-1482/) Proceedings of the 57th Annual Meeting of the Association for Computational Linguistics · no summary yet**Chen Wu et al.*2019 · 77 citations* 5. **[CodeElo: Benchmarking Competition-level Code Generation of LLMs with Human-comparable Elo Ratings ↗](https://arxiv.org/abs/2501.01257) arXiv:2501.01257 · no summary yet**Shanghaoran Quan et al.*2025 · 36 citations* 6. **[Qwen-Scope: Turning Sparse Features into Development Tools for Large Language Models ↗](https://arxiv.org/abs/2605.11887) arXiv:2605.11887 · no summary yet**Boyi Deng et al.*2026 · 3 citations* 7. **[LatentRefusal: Latent-Signal Refusal for Unanswerable Text-to-SQL Queries ↗](https://aclanthology.org/2026.findings-acl.1007/) Findings of the Association for Computational Linguistics: ACL 2026 · no summary yet**Xuancheng Ren et al.*2026* ## Co-authors here 8 co-authors with a page, the most papers together first. - [Xu Sun](https://md.research.elamur.ai/free/en/authors/xu-sun/) ×2 - [Houfeng Wang](https://md.research.elamur.ai/free/en/authors/houfeng-wang/) - [Jingjing Xu](https://md.research.elamur.ai/free/en/authors/jingjing-xu/) - [Lei Li](https://md.research.elamur.ai/free/en/authors/lei-li/) - [Wenjie Li](https://md.research.elamur.ai/free/en/authors/wenjie-li/) - [Wenkai Yang](https://md.research.elamur.ai/free/en/authors/wenkai-yang/) - [Xiaodong Zhang](https://md.research.elamur.ai/free/en/authors/xiaodong-zhang/) - [Zhiyuan Zhang](https://md.research.elamur.ai/free/en/authors/zhiyuan-zhang/) ## 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/) ×2: [ACL 2018](https://md.research.elamur.ai/free/en/venues/acl/2018/) - [Conference of the North American Chapter of the Association for Computational Linguistics (NAACL)](https://md.research.elamur.ai/free/en/venues/naacl/): [NAACL 2021](https://md.research.elamur.ai/free/en/venues/naacl/2021/) - Findings of the Association for Computational Linguistics: ACL 2026 - Proceedings of the 2018 Conference of the North American Chapter of the Association for Computational Linguistics: Human Language Technologies, Volume 1 (Long Papers) ## Cited by Papers of our library cite their works 6,590 times (of the 141,840 papers whose bibliographies we read); [248 citing papers with a page here →](https://md.research.elamur.ai/free/en/authors/xuancheng-ren/cited-by/).
