Problem types vary widely, and methods are tested on different datasets, metrics and settings, so it is hard to tell how much real progress has been made. This survey, by authors from Penn State and Temple University, organizes the field… 2. **[RetrievalAttention: Accelerating Long-Context LLM Inference via Vector Retrieval](https://md.research.elamur.ai/free/en/papers/liu-2024-retrievalattention-accelerating-long-context-llm/)** *(2024 · 66 citations)* Serving LLMs with very long contexts is expensive. Attention cost grows with sequence length, and the KV cache for Llama-3-8B reaches roughly 125GB at one million tokens, which no consumer GPU can hold. RetrievalAttention is a training-free method that exploits the fact that each decoding step depends strongly on… ## Co-authors here 11 co-authors with a page, the most papers together first. - [Chen Chen](https://md.research.elamur.ai/free/en/authors/chen-chen/) - [Chengruidong Zhang](https://md.research.elamur.ai/free/en/authors/chengruidong-zhang/) - [Fan Yang](https://md.research.elamur.ai/free/en/authors/fan-yang/) - [Huiqiang Jiang](https://md.research.elamur.ai/free/en/authors/huiqiang-jiang/) - [Kai Zhang](https://md.research.elamur.ai/free/en/authors/kai-zhang/) - [Meng Chen](https://md.research.elamur.ai/free/en/authors/meng-chen/) - [Qi Chen](https://md.research.elamur.ai/free/en/authors/qi-chen/) - [Renze Lou](https://md.research.elamur.ai/free/en/authors/renze-lou/) - [Rui Zhang](https://md.research.elamur.ai/free/en/authors/rui-zhang/) - [Wenpeng Yin](https://md.research.elamur.ai/free/en/authors/wenpeng-yin/) - [Zhenhua Han](https://md.research.elamur.ai/free/en/authors/zhenhua-han/) ## Venues Where their works here were published, the most works first, with the editions of those that have a page. - [Conference of the European Chapter of the Association for Computational Linguistics (EACL)](https://md.research.elamur.ai/free/en/venues/eacl/): [EACL 2024](https://md.research.elamur.ai/free/en/venues/eacl/2024/) - [Conference on Neural Information Processing Systems (NeurIPS)](https://md.research.elamur.ai/free/en/venues/neural-information-processing-systems/): [NeurIPS 2024](https://md.research.elamur.ai/free/en/venues/neural-information-processing-systems/2024/) ## Cited by Papers of our library cite their works 255 times (of the 149,439 papers whose bibliographies we read); [55 citing papers with a page here →](https://md.research.elamur.ai/free/en/authors/di-liu/cited-by/).
