Fig. 5: The confusion matrix of the three-dimensional triplet model for the first dataset.
From: Compact representations of microstructure images using triplet networks
The greyscale value indicates the number of images that belong to the material class shown on the x-axis and are assigned by the model to the material class shown on the y-axis. For the ideal model, only the diagonal would be coloured. The coloured boxes show the groups using the colourmaps that are defined in Table 1. The model mainly confuses materials belonging to the same group, which are visually very similar.
