RadEdit: stress-testing biomedical vision models via diffusion image editing

ECCV 2024poster

"Biomedical imaging datasets are often small and biased, meaning that real-world performance of predictive models can be substantially lower than expected from internal testing. This work proposes using generative image editing to simulate dataset shifts and diagnose failure modes of biomedical visi…

Exploring the Boundaries of GPT-4 in Radiology

EMNLP 2023long main

The recent success of general-domain large language models (LLMs) has significantly changed the natural language processing paradigm towards a unified foundation model across domains and applications. In this paper, we focus on assessing the performance of GPT-4, the most capable LLM so far, on the…

Learning To Exploit Temporal Structure for Biomedical Vision-Language Processing

CVPR 2023poster

Self-supervised learning in vision--language processing (VLP) exploits semantic alignment between imaging and text modalities. Prior work in biomedical VLP has mostly relied on the alignment of single image and report pairs even though clinical notes commonly refer to prior images. This does not onl…

Making the Most of Text Semantics to Improve Biomedical Vision-Language Processing

ECCV 2022poster

"Multi-modal data abounds in biomedicine, such as radiology images and reports. Interpreting this data at scale is essential for improving clinical care and accelerating clinical research. Biomedical text with its complex semantics poses additional challenges in vision-language modelling compared to…
