Chain of Risk: Safety Failures in Large Reasoning Models and Mitigation via Adaptive Multi-Principle Steering

Xiaomin Li, Jianheng Hou, Zheyuan Deng +6

Large reasoning models (LRMs) increasingly expose chain-of-thought-like reasoning for transparency, verification, and deliberate problem solving. This creates a safety blind spot:…

Selection of LLM Fine-Tuning Data based on Orthogonal Rules

Xiaomin Li, Mingye Gao, Zhiwei Zhang +2

High-quality training data is critical to the performance of large language models (LLMs). Recent work has explored using LLMs to rate and select data based on a small set of human…
