As a typical data augmentation method, a generative adversarial network is widely applied to solve data scarcity problems for imbalanced bearing fault diagnosis. However, these methods still face challenges in generating longer data due to the risk of mode collapse and instability during training. To address this issue, an enhanced generative adversarial network is proposed for generating longer vibration time data to improve imbalanced bearing fault diagnosis under variable operating conditions. Firstly, a dual cross-frequency attention block is integrated into the discriminator to adaptively...
