Looking Inside LLMs: Small-World Connectivity as a Signature of Reasoning Performance

Zheng Huang, Sansheng Cao, Enpei Zhang وآخرون · 2026

Understanding large language model (LLM) reasoning requires looking beyond behavioral performance to examine how reasoning ability is reflected in internal organization. Inspired by neuroscience findings linking higher intelligence to stronger small-world organization in functional brain networks, we investigate small- …

Overcoming Prior Barriers: Supervised Fine-Tuning under Long-Tail Distribution

Haohui Wang, Jiahao Xu, Wangzhi Zhan وآخرون · 2026

Supervised fine-tuning (SFT) adapts pretrained large language models (LLMs) to downstream tasks, but the required concepts can receive substantially different levels of pretrained support. Frequent concepts are more likely to be well learned, whereas rare concepts may remain weakly represented. We introduce a novel not …
