The paper introduces Test-Time Logit Prompting (TLP), a lightweight framework that adapts vision-language models to missing-modality inputs without accessing source training data. TLP optimizes logit prompts using uncertainty-aware adjustments and modality-complete consistency regularization, thereby maintaining prediction confidence and semantic consistency. Experiments on various benchmarks show that TLP improves recognition performance by up to 8% while requiring only a few hundred tunable parameters and minimal test-time optimization steps.

Vision-language models (VLMs) have achieved remarkable performance by leveraging complementary information from large-scale image-text pairs. However, missing-modality inputs are commonly encountered...
VISTA (Visually Impaired Scene and Task Annotations) is a multimodal egocentric benchmark designed to evaluate goal‑oriented assistance for blind and low‑vision users. It comprises about 1,000 recordings from Project Aria glasses, each providing six synchronized sensor streams and three types of annotations across ten task categories, from object localization to hazard detection. The benchmark tests vision‑language models in zero‑shot settings and introduces a lightweight multimodal baseline that integrates all six modalities, revealing that current models can describe scenes but struggle to generate effective assistive guidance.

The paper introduces FOCUS, a cross‑dataset benchmark for retinal fundus models that evaluates vision‑only encoders, vision‑language dual encoders, and multimodal large language models across ten public datasets. It measures ranking performance, calibration, subgroup disparities, and image‑quality robustness for tasks such as diabetic retinopathy and glaucomatous optic neuropathy. Results show no single model family dominates, with vision‑only encoders ranking highest on average, while fine‑tuning improves in‑domain performance but varies in external transfer.
