Masked Autoencoder learns steel defect recognition with 91.3% accuracy

Researchers have developed a novel unsupervised method for recognizing steel surface defects using a Transformer-based Masked Autoencoder. This approach learns representations from abundant unlabeled images by masking 75% of input patches and reconstructing them, achieving a structural similarity score of 0.92 and a mean squared error of 0.47. The learned features are then clustered using UMAP and Agglomerative clustering, resulting in a Hungarian matched accuracy of 91.3% against six known defect categories. AI

IMPACT This unsupervised approach could reduce the cost and effort of quality control in manufacturing by leveraging abundant unlabeled data.
