Supervised Fine-Tuning vs. In-Context Learning: An Equilibrium Analysis of LLM Personalization under Congestion

Fengzhuo Zhang, Zhuoran Yang, Dirk Bergemann

The paper studies when users of large language models should use expensive supervised fine-tuning versus lightweight in‑context learning, considering how other users' choices creat…

INFUSER: Influence-Guided Self-Evolution Improves Reasoning

Siyu Chen, Miao Lu, Beining Wu +7

Self-evolution offers a scalable path to stronger reasoning: a pretrained language model improves itself with only minimal external supervision. Yet existing methods either depend…

Muon Learns More Robust and Transferable Features than Adam

Tianyu Ruan, Fengzhuo Zhang, Shuche Wang +1

Muon has recently emerged as a state-of-the-art optimizer for pretraining Large Language Models (LLMs) and vision classifiers. Despite its efficiency advantage over Adam and SGD, t…

Why Muon Outperforms Adam: A Curvature Perspective

Shuche Wang, Fengzhuo Zhang, Jiaxiang Li +2

Muon improves training efficiency over Adam in large language-model training by about two times, but the local geometric source of this advantage remains unclear. Our work takes a…

Sparse-to-Dense: A Free Lunch for Lossless Acceleration of Video Understanding in LLMs

Xuan Zhang, Cunxiao Du, Sicheng Yu +4

Due to the auto-regressive nature of current video large language models (Video-LLMs), the inference latency increases as the input sequence length grows, posing challenges for the…

LongSpec: Long-Context Lossless Speculative Decoding with Efficient Drafting and Verification

Penghui Yang, Cunxiao Du, Fengzhuo Zhang +4

As Large Language Models (LLMs) can now process extremely long contexts, efficient inference over these extended inputs has become increasingly important, especially for emerging a…
