basis of data expansion and feature enhancement of vibration signals of rolling bearings. ResNet34 deep network was used to diagnose and classify the small sample unbalance fault of one ̄dimensional vibration signals. The experimental results show that as the small sample unbalanced data set gradually expands to the multi ̄dimensional balanced data set. the accuracy of the proposed method in different data sets is effectively improved. and the classification accuracy reaches 99. 5%. which proves that the feature extraction capability of the proposed
method is superior to the typical machine learning and deep learning neural network. thus verifying the advantages of the method in the small sample unbalanced fault diagnosis.
Key words: small sample fault diagnosis;data expansion. deep learning; generating adversarial networks(GAN); residual structure(RS);conditional convolution generates adversarial networks (CCGAN);improved feature extraction enhancements (IFEE) method
