Problems solved by technology

[0003] However, with the continuous expansion of the application scope of deep learning, its vulnerability in the face of adversarial examples needs to be resolved urgently.
Deep learning technology is generally vulnerable to adversarial samples. The disturbed sample input causes the model to give a wrong output with high confidence. In many cases, training on different subsets of the training set has different structures. The model will misclassify the same adversarial example, which means that the adversarial example becomes a blind spot of the training algorithm
