Train (labeled normal, gestational birth age of 39 weeks) anomaly detection map for vae_8x8_512 across each standard deviation range. The first column shows slices without anomaly overlays, and the subsequent columns represent the model outputs overlayed by range of absolute standard deviations for clarity. We consider standard deviations that are within the following ranges: 2 to 3, 3 to 4, and 4 to infinity, where the higher standard deviations indicate a greater potential severity of anomaly (divergence from normal appearance). Positive standard deviations of the reconstruction error map are indicated in shades of red and negative standard deviations are indicated in shades of blue.
