摘要:

自动化可解释性系统旨在减少人工劳动并扩展到更大模型和多样任务。最近的努力利用大语言模型(LLMs)提高自主性,从固定的一次性流程到完全自主的可解释性代理。这种转变需要扩展评估方法以匹配生成解释的规模和复杂性。我们在此背景下研究了自动化电路分析中的可解释性问题,构建了一个代理系统,其中研究代理迭代设计实验并细化假设。在六个文献中的电路分析任务中,该系统在人类专家解释的评估中表现竞争。然而,更深入的检查揭示了基于复制的评估的几个陷阱:人类专家解释可能是主观或不完整的,基于结果的比较模糊了研究过程,且基于LLM的系统可能通过记忆或有意识猜测重现已发表的发现。为解决一些陷阱,我们提出了一种基于模型组件功能互换性的无监督内在评估。我们的工作展示了评估复杂自动化可解释性系统的基本挑战,并揭示了复制评估的关键限制。

英文摘要:

Automated interpretability systems aim to reduce the need for human labor and scale analysis to increasingly large models and diverse tasks. Recent efforts toward this goal leverage large language models (LLMs) at increasing levels of autonomy, ranging from fixed one-shot workflows to fully autonomous interpretability agents. This shift creates a corresponding need to scale evaluation approaches to keep pace with both the volume and complexity of generated explanations. We investigate this challenge in the context of automated circuit analysis -- explaining the roles of model components when performing specific tasks. To this end, we build an agentic system in which a research agent iteratively designs experiments and refines hypotheses. When evaluated against human expert explanations across six circuit analysis tasks in the literature, the system appears competitive. However, closer examination reveals several pitfalls of replication-based evaluation: human expert explanations can be subjective or incomplete, outcome-based comparisons obscure the research process, and LLM-based systems may reproduce published findings via memorization or informed guessing. To address some of these pitfalls, we propose an unsupervised intrinsic evaluation based on the functional interchangeability of model components. Our work demonstrates fundamental challenges in evaluating complex automated interpretability systems and reveals key limitations of replication-based evaluation.
