Figure 12From: Mechanical assessment of defects in welded joints: morphological classification and data augmentationLeft column: confusion matrices for the training (rows a, c) and testing sets (rows b, d) between Grassmann clustering (true label) and the label predicted by the dense neural network using the signed (rows a, b) and spherical harmonics distances (rows c, d). Right: percentage of misclassified shapes in each clusterBack to article page
