Role-Sensitive Neurons: A Neuron-Level Gain Control Mechanism for Confidence Steering
Peiwen Huang · Chih-Hao Hsu · Tzu-Hung Huang · Shou-De Lin
摘要
Role-playing prompts effectively steer Large Language Models (LLMs), yet the neural mechanism driving this behavioral shift remains unclear. In this work, we identify Role-Sensitive Neurons (RSNs)—a sparse sub-network (≈ 0.5% of all neurons) governing the transition from hesitation to action. Usi...
