arXiv:2606.22649v2 Announce Type: replace-cross Abstract: Foundation models provide highly descriptive representations for medical images, yet their reliability degrades under distribution shifts arising from changes in patients, devices, or acquisition conditions. Reliable out-of-distribution (OOD) detection is therefore essential for safe deployment. Recent post-hoc detectors efficiently exploit frozen embeddings (e.g., kNN), whereas reconstruction-based OOD detection in latent feature space has seen limited adoption due to inconsistent performance. In this work, we show that the limitation
The proliferation of foundation models in critical applications like medical imaging necessitates robust safety mechanisms to ensure reliable performance under diverse real-world conditions.
Improved out-of-distribution (OOD) detection is crucial for the safe and ethical deployment of AI in high-stakes fields, directly impacting public trust and regulatory acceptance.
This research introduces a more consistent and efficient method for OOD detection, potentially accelerating the adoption of foundation models in sensitive domains by enhancing their reliability.
