GeoDiv: Framework For Measuring Geographical Diversity In Text-To-Image Models

The paper introduces GeoDiv, a novel framework leveraging large language and vision-language models to systematically measure and reveal significant geographical biases and socio-economic stereotypes in text-to-image generation, demonstrating how current models disproportionately portray countries like India, Nigeria, and Colombia in impoverished ways.

WeaveTime: Stream from Earlier Frames into Emergent Memory in VideoLLMs

WeaveTime is a model-agnostic framework that addresses the time-agnostic limitations of current Video-LLMs in streaming scenarios by introducing a lightweight Temporal Reconstruction objective to instill order-aware representations and a Past-Current Dynamic Focus Cache for uncertainty-triggered retrieval, thereby improving accuracy and reducing latency without architectural changes.

UWF-RI2FA: Generating Multi-frame Ultrawide-field Fluorescein Angiography from Ultrawide-field Retinal Imaging Improves Diabetic Retinopathy Stratification

This study presents UWF-RI2FA, a generative AI model that synthesizes realistic, multi-frame, dye-free ultrawide-field fluorescein angiography images from noninvasive retinal imaging, significantly improving diabetic retinopathy stratification accuracy compared to using retinal imaging alone.

Two Models for Surface Segmentation using the Total Variation of the Normal Vector

This paper proposes a variational approach for surface segmentation on triangular meshes that compares two total variation regularizers, demonstrating that a label-space regularizer yields superior noise removal at the cost of higher computation, which is mitigated by introducing a manifold Newton scheme to efficiently solve the associated Riemannian center of mass problem.
