Techniques deriving interpretable descriptions of LLM Activations and internal model states without human-labeled supervision, often utilizing latent representations from Autoencoders.
- Natural Language Autoencoders: Research from transformer-circuits.pub demonstrates that natural language autoencoders can reconstruct activations using interpretable features, producing unsupervised explanations of LLM behavior via mapping to natural language tokens.
