Fig. 7

Terminal villi are primarily high attention (yellow, regions 1, 5, and 6). Basal plate (left side of WSI and region 2), stem villi (region 3, intermixed with villous areas) and chorionic plate (right side of WSI and region 4) are generally low attention (purple). Estimated gestational age shows variegation with accurate areas (region 1) intermixed with areas with inaccurate low (blue, region 2) and high (red, region 3) estimates. Areas with low attention are disregarded (grayscale). The model is not explicitly trained to recognize tissue types and shows erroneous high attention to some areas. For example, one chorionic plate vessel (region 4) is part high- and part low-attention. The attended part of the vessel wall gives an estimate that misses low. Intravascular blood is attended and misses high.
