arXiv:2607.04222v1 Announce Type: new Abstract: Interpretability methods aim to reveal the features represented inside large language models (LLMs). Many existing methods begin with labeled examples of a human-defined concept that may reflect human biases, and then identify how that concept is represented within the model, for example in its activation space or through other decomposition methods. We introduce \emph{Mining via Activation Geometry} (MAG), a simple unsupervised framework for extracting reasoning features from model activations by prepending the same natural-language instruction
The continuous development and scaling of LLMs necessitate more sophisticated interpretability methods to understand their internal workings and mitigate biases, making research into unsupervised feature extraction highly relevant.
This development proposes a method to extract reasoning features from LLMs without relying on human-labeled data, potentially leading to more robust, less biased, and more transparent AI systems.
The ability to mine features directly from activation geometry could reduce the dependency on human-defined concepts for interpretability, offering a more intrinsic understanding of AI's internal logic.
