A recent audit of anomaly detection experiments using frozen encoders has revealed issues with representation provenance and calibration. The study found that while numerical discrimination results were reproducible, the claimed attribution to interferometric pretraining was not supported. Embeddings labeled as interferometric showed norms comparable to freshly initialized networks, differing significantly from preserved ImageNet embeddings. Further analysis indicated that these near-zero embeddings produced similar anomaly scores, suggesting an architecture-and-initialization effect rather than cross-domain transfer. AI
