When sentence embeddings are extracted from them without fine-tuning, tokens near the start of the input cannot see later tokens. Prompt-based methods such as PromptEOL read the embedding from the final prompt token, but that token still inherits the skewed representations… 2. **[Contrastive Prompting Enhances Sentence Embeddings in LLMs through Inference-Time Steering](https://md.research.elamur.ai/free/en/papers/cheng-2025-contrastive-prompting-enhances-sentence-embeddings/)** *(2025 · 8 citations)* Large language models can produce sentence embeddings without any training data or fine-tuning: a prompt wraps the sentence, and the hidden state of the final token serves as the vector. 3. **[AEA: Adaptive Expert Allocation Improves Sentence Embeddings from Mixture-of-Experts LLM](https://md.research.elamur.ai/free/en/papers/yang-2026-aea-adaptive-expert-allocation-improves/)** *(2026)* The paper addresses training-free sentence embeddings taken directly from Mixture-of-Experts (MoE) LLMs. Earlier work, such as MoEE, keeps the same Top-K number of experts for every layer and every token. The authors show that this uniform budget wastes capacity. In DeepSeekMoE-16B and OLMoE-1B-7B, expert outputs are… ## Co-authors here 7 co-authors with a page, the most papers together first. - [Qing Gu](https://md.research.elamur.ai/free/en/authors/qing-gu/) ×3 - [Zhiwei Jiang](https://md.research.elamur.ai/free/en/authors/zhiwei-jiang/) ×3 - [Zifeng Cheng](https://md.research.elamur.ai/free/en/authors/zifeng-cheng/) ×3 - [Cong Wang](https://md.research.elamur.ai/free/en/authors/cong-wang/) ×2 - [Yuchen Fu](https://md.research.elamur.ai/free/en/authors/yuchen-fu/) ×2 - [Zhonghui Wang](https://md.research.elamur.ai/free/en/authors/zhonghui-wang/) ×2 - [Ao Zhou](https://md.research.elamur.ai/free/en/authors/ao-zhou/) ## 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/) ×3: [ACL 2026](https://md.research.elamur.ai/free/en/venues/acl/2026/), [ACL 2025](https://md.research.elamur.ai/free/en/venues/acl/2025/) ×2 ## Cited by Papers of our library cite their works 17 times (of the 149,439 papers whose bibliographies we read); [6 citing papers with a page here →](https://md.research.elamur.ai/free/en/authors/yafeng-yin/cited-by/).
