Vector Quantized Latent Concepts: A Scalable Alternative to Clustering-Based Concept Discovery
Researchers have introduced Vector Quantized Latent Concept (VQLC), a new framework for interpreting large language models by extracting latent concepts from their hidden states. This method aims to overcome the limitations of existing clustering techniques, which either scale poorly or produce less coherent concepts. VQLC offers a computationally efficient and scalable alternative that demonstrates competitive faithfulness and interpretability, particularly for decoder-only models. AI
