Test (labeled abnormal, gestational birth age of 37 weeks) anomaly detection map for vae_8x8_512 across each standard deviation range. Positive standard deviations of the reconstruction error map are indicated in shades of red and negative standard deviations are indicated in shades of blue. In this example, the peripheral and deep white space as well as asymmetric fluid space (\(3^{+}\) standard deviations, arrow 1) is indicative of volume loss in the left hemisphere. We also see hemorrhage along the tentorium and occipital region (2–4 standard deviations, arrow 2).
