Vision Language Models are Biased

ICLR 2026poster

Large language models (LLMs) memorize a vast amount of prior knowledge from the Internet that helps them on downstream tasks but also may notoriously sway their outputs towards wrong or biased answers. In this work, we test how the knowledge about popular subjects hurt the accuracy of vision languag…

B-score: Detecting biases in large language models using response history

ICML 2025poster

Large language models (LLMs) often exhibit strong biases, e.g, against women or in favor of the number 7. We investigate whether LLMs would be able to output less biased answers when allowed to observe their prior answers to the same question in a multi-turn conversation. To understand which types o…

CT-ScanGaze: A Dataset and Baselines for 3D Volumetric Scanpath Modeling

ICCV 2025poster

Understanding radiologists' eye movement during Computed Tomography (CT) reading is crucial for developing effective interpretable computer-aided diagnosis systems. However, CT research in this area has been limited by the lack of publicly available eye-tracking datasets and the three-dimensional co…

TAB: Transformer Attention Bottlenecks enable User Intervention and Debugging in Vision-Language Models

ICCV 2025poster

Multi-head self-attention (MHSA) is a key component of Transformers, a widely popular architecture in both language and vision. Multiple heads intuitively enable different parallel processes over the same input. Yet, they also obscure the attribution of each input patch to the output of a model. We…

ImageNet-Hard: The Hardest Images Remaining from a Study of the Power of Zoom and Spatial Biases in Image Classification

NeurIPS 2023poster

Image classifiers are information-discarding machines, by design. Yet, how these models discard information remains mysterious. We hypothesize that one way for image classifiers to reach high accuracy is to first zoom to the most discriminative region in the image and then extract features from ther…

Visual correspondence-based explanations improve AI robustness and human-AI team accuracy

NeurIPS 2022accept

Explaining artificial intelligence (AI) predictions is increasingly important and even imperative in many high-stake applications where humans are the ultimate decision-makers. In this work, we propose two novel architectures of explainable image classifiers that first explain, and then predict (as…

The effectiveness of feature attribution methods and its correlation with automatic evaluation scores

NeurIPS 2021poster

Explaining the decisions of an Artificial Intelligence (AI) model is increasingly critical in many real-world, high-stake applications. Hundreds of papers have either proposed new feature attribution methods, discussed or harnessed these tools in their work. However, despite humans being the target…
