A new research paper titled "Are We Recovering Mechanisms? Objective-Level Recovery Gaps in Mechanistic Interpretability" has been published on arXiv. The paper investigates the effectiveness of current methods in mechanistic interpretability, which aims to understand the internal computations of AI models. Researchers found that evaluation objectives can sometimes favor less accurate circuits, creating an "objective-level recovery gap." This gap was observed across various tasks and methods, with a significant percentage of candidate pairs being misranked. The study suggests that context distortion, where changes in input affect retained components, contributes to this issue. Restoring specific signals from the intact model's execution was shown to correct most of these misrankings without altering the circuits or their original behavioral scores. AI
