Composed Vision-Language Retrieval for Skin Cancer Case Search via Joint Alignment of Global and Local Representations

This paper proposes a transformer-based framework for skin cancer case retrieval that effectively combines reference images and textual descriptors by learning hierarchical representations and performing joint global-local alignment, thereby achieving state-of-the-art performance on the Derm7pt dataset to support clinical decision-making.

Gender Fairness in Audio Deepfake Detection: Performance and Disparity Analysis

This paper analyzes gender bias in audio deepfake detection using the ASVspoof 5 dataset and a ResNet-18 classifier, demonstrating that while aggregate metrics like Equal Error Rate may suggest low disparity, fairness-aware evaluation reveals significant gender-specific error distributions that necessitate more equitable and robust detection systems.
