With large batches and long contexts, though, the KV cache becomes the main memory and speed bottleneck: it can exceed the size of the model weights, and the GPU must read it in full for every generated token. The authors examine how values are distributed inside the… 2. **[Language Ranker: A Metric for Quantifying LLM Performance Across High and Low-Resource Languages](https://md.research.elamur.ai/free/en/papers/li-2024-language-ranker-metric-quantifying-llm/)** *(2024 · 95 citations)* LLMs are trained on corpora dominated by English. For example, about 92.65% of GPT-3 tokens and 89.7% of LlaMa2 pre-training data are English. As a result, low-resource languages get weaker support, yet there are few quantitative ways to measure this gap. The authors propose Language Ranker, an intrinsic metric that… 3. **[LLM Maybe LongLM: Self-Extend LLM Context Window Without Tuning](https://md.research.elamur.ai/free/en/papers/jin-2024-llm-maybe-longlm-self-extend/)** *(2024 · 78 citations)* Large language models that use RoPE usually fail on inputs longer than their pretraining sequence length. Perplexity spikes and outputs become erratic. In this ICML 2024 paper, the authors argue that the problem is not a lack of long-text understanding. Instead, they blame a "positional O.O.D." effect: at inference… ## Co-authors here 10 co-authors with a page, the most papers together first. - [Hongye Jin](https://md.research.elamur.ai/free/en/authors/hongye-jin/) ×2 - [Xia Hu](https://md.research.elamur.ai/free/en/authors/xia-hu/) ×2 - [Beidi Chen](https://md.research.elamur.ai/free/en/authors/beidi-chen/) - [Fan Yang](https://md.research.elamur.ai/free/en/authors/fan-yang/) - [Jiayi Yuan](https://md.research.elamur.ai/free/en/authors/jiayi-yuan/) - [Jingfeng Yang](https://md.research.elamur.ai/free/en/authors/jingfeng-yang/) - [Mengnan Du](https://md.research.elamur.ai/free/en/authors/mengnan-du/) - [Ninghao Liu](https://md.research.elamur.ai/free/en/authors/ninghao-liu/) - [Shaochen Zhong](https://md.research.elamur.ai/free/en/authors/shaochen-zhong/) - [Xiaotian Han](https://md.research.elamur.ai/free/en/authors/xiaotian-han/) ## Venues Where their works here were published, the most works first, with the editions of those that have a page. - [Proceedings of the AAAI Conference on Artificial Intelligence](https://md.research.elamur.ai/free/en/venues/proceedings-of-the-aaai-conference-on-artificial-intelligence/): [Proceedings of the AAAI Conference on Artificial Intelligence 2024](https://md.research.elamur.ai/free/en/venues/proceedings-of-the-aaai-conference-on-artificial-intelligence/2024/) ## Cited by Papers of our library cite their works 355 times (of the 141,840 papers whose bibliographies we read); [17 citing papers with a page here →](https://md.research.elamur.ai/free/en/authors/zirui-liu/cited-by/).
