What is mechanistic interpretability in language models?
Mechanistic interpretability in language models refers to the process of identifying and analyzing specific computational subgraphs, known as circuits, which capture particular aspects of a model's behavior. This approach aims to better understand the inner workings of complex language models and has potential applications in making AI models safer by removing unwanted biases3.
What are the limitations of the ACDC method?
The ACDC method has limitations such as its greedy search approach, which is computationally expensive and doesn't scale well to large datasets or billion-parameter models. Additionally, ACDC relies on inefficient search algorithms and sacrifices faithfulness to the full model by using gradient-based linear approximations. These challenges hinder the progress of mechanistic interpretability and limit the ability to understand the inner workings of complex language models.
