The design of the Transformer block itself gets little attention, even though large models are costly to run. The authors study LLaMA-style decoders and identify feature collapse: a rank metric shows token representations growing more… 2. **[Pangu Ultra MoE: How to Train Your Big MoE on Ascend NPUs](https://md.research.elamur.ai/free/en/papers/tang-2025-pangu-ultra-moe-train/)** *(2025 · 8 citations)* Training MoE language models with nearly a trillion parameters is hard: the hardware is underused because the set of experts each token activates changes at runtime, and the scale strains communication and memory. 3. **[PanGu-π Pro:Rethinking Optimization and Architecture for Tiny Language Models](https://md.research.elamur.ai/free/en/papers/tang-2024-pangu-pi-pro-rethinking/)** *(2024 · 8 citations)* On-device deployment needs small language models that still perform well. Most tiny models, however, simply reuse recipes designed for much larger LLMs, and few studies test which of those choices actually suit a ~1B-parameter model. The authors run a systematic set of ablations on a 1B LLaMA-style baseline, trained… 4. **[Pangu Pro MoE: Mixture of Grouped Experts for Efficient Sparsity](https://md.research.elamur.ai/free/en/papers/tang-2025-pangu-pro-moe-mixture/)** *(2025 · 4 citations)* Sparse Mixture-of-Experts LLMs are cheap per token. However, when experts are spread across accelerators, uneven routing overloads some devices, and the slowest device limits overall speed. The Pangu Team at Huawei proposes Mixture of Grouped Experts (MoGE). Experts are split into equal, non-overlapping groups… ## Co-authors here 12 of 17 co-authors with a page, the most papers together first. - [Yehui Tang](https://md.research.elamur.ai/free/en/authors/yehui-tang/) ×4 - [Kai Han](https://md.research.elamur.ai/free/en/authors/kai-han/) ×3 - [Hang Zhou](https://md.research.elamur.ai/free/en/authors/hang-zhou/) ×2 - [Wei Guo](https://md.research.elamur.ai/free/en/authors/wei-guo/) ×2 - [Yaoyuan Wang](https://md.research.elamur.ai/free/en/authors/yaoyuan-wang/) ×2 - [Yunhe Wang](https://md.research.elamur.ai/free/en/authors/yunhe-wang/) ×2 - [Zheyuan Bai](https://md.research.elamur.ai/free/en/authors/zheyuan-bai/) ×2 - [Fei Mi](https://md.research.elamur.ai/free/en/authors/fei-mi/) - [Hanting Chen](https://md.research.elamur.ai/free/en/authors/hanting-chen/) - [Jinpeng Li](https://md.research.elamur.ai/free/en/authors/jinpeng-li/) - [Tianyu Guo](https://md.research.elamur.ai/free/en/authors/tianyu-guo/) - [Xianzhi Yu](https://md.research.elamur.ai/free/en/authors/xianzhi-yu/) ## Cited by Papers of our library cite their works 28 times (of the 149,439 papers whose bibliographies we read); [4 citing papers with a page here →](https://md.research.elamur.ai/free/en/authors/fangcheng-liu/cited-by/).
