Evaluating the Interpretability of Sparse Autoencoders with Concept Annotations

arXiv:2606. 24716v1 Announce Type: cross Abstract: Sparse autoencoders (SAEs) are increasingly used to extract interpretable concepts from vision and vision language models, yet existing evaluation methods largely rely on proxy metrics or qualitative inspection rather than measuring semantic correspondence.

Revealing the Gap in Human and VLM Scene Description through Counterfactual Semantic Saliency

The paper introduces Counterfactual Semantic Saliency (CSS), a black-box, model-agnostic method that measures how the removal of objects from a scene shifts the semantic description produced by vision‑language models (VLMs). Using CSS, the authors compare prominent VLMs to a large human psychophysics baseline (16,603 responses across 307 scenes) and find that VLMs over‑rely on large, centrally located, and highly salient objects, while under‑rely on people compared to humans. The study highlights a significant scene‑comprehension gap between VLMs and human perception, with size bias emerging as a key factor driving model‑human divergence.

Seeing or Knowing? Visual Context Sensitivity in Multimodal Large Language Models

The paper investigates why multimodal large language models (MLLMs) struggle with vision‑centric tasks when visual evidence conflicts with pretrained language knowledge. Using image reconstruction and a new WhatIfVis benchmark, the authors show that MLLMs preserve coarse‑grained visual attributes but fail to consistently use them, and that supervised fine‑tuning and activation patching can improve controllability of visual context sensitivity. The study demonstrates that the main bottleneck lies in the models’ inability to reliably regulate their reliance on visual evidence rather than in visual perception itself.
