Figure 17From: Mechanical assessment of defects in welded joints: morphological classification and data augmentationLeft column: confusion matrices for the training (rows 1, 3) and testing sets (rows 2, 4) showing the true Grassmann clustering label vs. the label predicted by the neural network using the morphological (rows 1, 2) and spherical-harmonics distance (rows 3, 4). Right: percentage of misclassified shapes in each cluster after data augmentationBack to article page
