DCA-BiGRU
The pytorch implementation of the paper Fault diagnosis for small samples based on attention mechanism
However, in fact, the title Fault diagnosis for small samples based on interpretable improved space-channel attention mechanism and improved regularization algorithms fits the research content of the paper better.
The dataset comes from 12khz, 1hp
Contributions:
- 1D-signal attention mechanism [code]
- AMSGradP [code]
- 1D-Meta-ACON [code]
- At the beginning, I found that many model designs did not connect GAP operation after BiGRU/BiLSTM, which is the basically routine operation. I found that GAP works very well. [code]
- 1D-Grad-CAM++ [code]
- AdaBN [code]
