New research reveals pipeline choices skew AI interpretability scores

A new paper published on arXiv highlights significant variance in autointerpretability scores used for comparing sparse autoencoders (SAEs) in language models. Researchers found that differences in evaluation pipelines, rather than model architectures, largely account for score variations across metrics like simulation, detection, and fuzzing. The study also revealed that top-k feature rankings can be inconsistent, masking underlying instability. To address these issues, the authors propose a variance decomposition approach, a Stability Check, and a Minimum Reporting Checklist to improve the reliability of interpretability research. AI
