Researchers have introduced Mining via Activation Geometry (MAG), an unsupervised framework designed to extract reasoning features from large language models (LLMs). Unlike existing methods that rely on labeled examples, MAG uses natural-language instructions prepended to inputs to identify how specific reasoning features are represented internally. The extracted features can predict a model's understanding and judgment, and can be used to steer the LLM's decisions through activation steering. This method also proved effective in selecting optimal training datasets for prompt-injection classifiers, achieving high accuracy. AI
IMPACT Provides a novel unsupervised approach to understanding internal LLM reasoning, potentially improving model interpretability and control.
