arXiv Paper Proposes Hierarchy-Grounded Domains for Clinical Domain Generalization

A new arXiv preprint introduces a method that organizes clinical data into hierarchy-based domains with adjustable granularity, aiming to improve model generalization across shifting patient populations. The authors argue that standard domain generalization techniques fall short in healthcare settings, where data distributions vary between patient groups. The work was posted as a replacement version on arXiv's machine learning and AI categories.

Spectral and Activation Clustering Combined for Backdoor Detection in Medical Imaging Models

A new arXiv paper proposes combining spectral signatures of model weights with clustering of internal activations to detect backdoors planted in healthcare imaging models during training. The authors frame the work around sector-level guidance that names model poisoning and adversarial manipulation as concerns for clinical machine learning deployments. The paper covers the method, its implementation, and an evaluation of detection performance.
