New research tackles interpretability challenges in sparse autoencoders · 2 papers

By PulseAugur Editorial · [3 sources] ·

Two new research papers address challenges in interpreting large language models using sparse autoencoders (SAEs). The first paper introduces C$^2$R (Cross-sample Consistency Regularization) to mitigate feature splitting and absorption, issues that arise from inconsistent latent assignments across samples. The second paper identifies and addresses cross-modal feature heterogeneity in vision-language models, where the same concept can activate different latent directions depending on whether it's represented in image or text embeddings.

    C$^{2}$R: Cross-sample Consistency Regularization Mitigates Feature Splitting and Absorption in Sparse Autoencoders

    arXiv:2606.30609v1 Announce Type: cross Abstract: Sparse Autoencoders (SAEs) are widely used to interpret large language models by decomposing activations into sparse, human-understandable features, but scaling to large dictionaries exposes fundamental challenges. Systematic stud…

    Same Concept, Different Directions: Cross-Modal Feature Heterogeneity in Sparse Autoencoders

    arXiv:2606.29888v1 Announce Type: new Abstract: Vision-language models map images and text into a joint embedding space. However, these embeddings often entangle multiple semantic features, which limits their interpretability and controllability. While sparse autoencoders have em…
