New method corrects attribution patching errors in language models

Researchers have developed a new method to improve the accuracy of attribution patching, a technique used to understand how different parts of a language model contribute to its behavior. The current method, a first-order approximation, can be unreliable due to network non-linearities. The new approach introduces a second-order correction using Hessian-vector products, which significantly enhances the fidelity of circuit recovery. This method is computationally feasible for larger models and offers practical tools for detecting untrustworthy estimates and quantifying errors. AI
