Fig. 4: Visualisation of the embedding space at slide and patch levels.
From: H&E-based MSI/MMR testing with AI in colorectal cancer: a multi-centred blinded evaluation
The embedding space of 61 whole slide images (WSIs) from the L1-UK-CRC-SVS-1-BLIND cohort is visualised at both slide (A) and patch (B) levels. MSI-H/dMMR and non-MSI-H/pMMR images and patches are shown in red and blue, respectively. The slide level embeddings (A) are visualised using 2D t-SNE, while the top 100 scoring attention tiles per WSI (B) are visualised using 3D t-SNE. An example of three closest MSI-H/dMMR and non-MSI-H/pMMR patches (based on cosine distance) is shown, taken from regions indicated by red and blue boxes, respectively.
