GeoDiv: Framework for Measuring Geographical Diversity in Text-to-Image Models

ICLR 2026poster

Text-to-image (T2I) models are rapidly gaining popularity, yet their outputs often lack geographical diversity, reinforce stereotypes, and misrepresent regions. Given their broad reach, it is critical to rigorously evaluate how these models portray the world. Existing diversity metrics either rely o…

Harnessing Diffusion-Generated Synthetic Images for Fair Image Classification

AAAI 2026technical

Image classification systems often inherit biases from uneven group representation in training data. For example, in face datasets for hair color classification, blond hair may be disproportionately associated with females, reinforcing stereotypes. A recent approach leverages the Stable Diffusion mo

Balancing Act: Distribution-Guided Debiasing in Diffusion Models

CVPR 2024poster

Diffusion Models (DMs) have emerged as powerful generative models with unprecedented image generation capability. These models are widely used for data augmentation and creative applications. However DMs reflect the biases present in the training datasets. This is especially concerning in the contex…

Mitigating Biases in Blackbox Feature Extractors for Image Classification Tasks

NeurIPS 2024poster

In image classification, it is common to utilize a pretrained model to extract meaningful features of the input images, and then to train a classifier on top of it to make predictions for any downstream task. Trained on enormous amounts of data, these models have been shown to contain harmful biases…

Inspecting the Geographical Representativeness of Images from Text-to-Image Models

ICCV 2023poster

Recent progress in generative models has resulted in models that produce both realistic as well as relevant images for most textual inputs. These models are being used to generate millions of images everyday, and hold the potential to drastically impact areas such as generative art, digital marketin…

RMLVQA: A Margin Loss Approach for Visual Question Answering With Language Biases

CVPR 2023poster

Visual Question Answering models have been shown to suffer from language biases, where the model learns a correlation between the question and the answer, ignoring the image. While early works attempted to use question-only models or data augmentations to reduce this bias, we propose an adaptive mar…
