Abstract

A convolutional neural network (CNN) is proposed to learn multiple useful feature representations for a classification from low level (raw pixels) to high level (object).Convolutional kernels are initialized by the learned filter kernels that come from sparse auto-encoders.Unlike some traditional methods, which divide the feature abstracting and classifier training into two separated processes, a discriminative feature vector and a single multi-class classifier of softmax regression are learned simultaneously during the training process.Based on the learned high-quality feature representation, the classification can be efficiently performed.A real-world case of surface defects on steel sheet, which evaluates the classification performance of the proposed method, is depicted in detail.The experimental results indicate that the proposed method is quite simple, effective and robustness for the classification of surface defects on hot-rolled steel sheet.

  • Because all local parts share weights, CNN does not take into account the difference of contribution to the whole between each local part.

    “Because all local parts share weights, it does not take into account the difference of contribution to the whole between each local part.”
  • Compared with a fully connected network, CNN reduces many parameters and simplifies calculation by adopting local connection, weight sharing and down sampling operations.

    “Compare with fully connected network, it reduces many parameters and simplifies the calculation by adopting local connection, weight sharing and down sampling operations.”
  • A CNN adopted as a classifier for defect classification of flat steel surfaces was found in experimental results to be powerful and robust for the classification task.

    “In [104] and [105], a CNN was adopted as a classifier for the defect classification of flat steel surfaces, and the experimental results indicate that the CNN is powerful and robust for the classification task.”
  • Deep learning methods such as CNN, GAN, and AutoEncoder have achieved outstanding performance in both feature learning and defect recognition for flat steel surfaces.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
