New framework uses neuron activations for LLM few-shot learning

Researchers have developed NeuFS, a novel framework for Neuron-Aware Active Few-Shot Learning designed to enhance the adaptation of Large Language Models (LLMs) to specialized domains. Unlike existing methods that rely on output-level signals, NeuFS leverages internal neuron activation patterns to identify the most valuable unlabeled samples for annotation. This approach ensures diversity in few-shot samples and prioritizes challenging examples that LLMs tend to hallucinate, by quantifying neuron consensus. Experiments show NeuFS outperforms current active few-shot learning baselines in reasoning and text classification tasks, demonstrating the effectiveness of internal neuron activations over external embeddings.
