Researchers build knowledge graphs from sparse autoencoder features for model interpretability

Researchers have developed a method to transform sparse autoencoder (SAE) features into structured knowledge graphs. This process involves creating a domain-specific concept universe from SAE features and then building two graph views: one based on co-occurrence and another linking features through latent pathways. Automated labeling further enhances these graphs, enabling a clearer understanding of a language model's internal knowledge and reasoning processes, as demonstrated in a case study using a biology textbook.
