Model interpretation using tile-level embeddings and whole-slide spatial heatmaps. A, UMAP visualization of tile-level histopathology embeddings extracted from H&E-stained WSIs. Points are colored by unsupervised embedding cluster and shaped according to model-defined risk group. B, Distribution of model-predicted risk scores across embedding clusters. Boxplots indicate the median and interquartile range, with pairwise comparison P values shown. C, Representative image tiles from each embedding cluster, illustrating morphologic patterns captured by the image feature extractor.
