On the other hand, a 𝐾K value exceeding 5 increases the complexity of the calculation significantly, introducing the risk of over-decomposition. Such a scenario is not optimal for prompt fault diagnosis due to the increased computational demands and potential for muddled insights. To strike a ...
The calculation was completed within 3.6 s for each trial. The performance of method was assessed by the metrics of mean and standard deviation. (1) Fault Diagnosis of Planetary Gear Table 9 presents the results of different methods for fault diagnosis of gear under cross conditions. SDAA ...
Finally, the signal-to-noise ratio (SNR) of EWT, EMD, EWT-SVD, and EMD-like improved algorithms is obtained using calculation, and the results are shown in Table 2. The findings reveal that the SNR of EWT-SVD markedly surpasses that of EWT, reinforcing the merits of integrating the SVD...
The structure and parameters of ANN need to be set artificially, which leads to low generalization ability; Kernel function selection for SVM/RVM with different objects is a huge challenge. Calculation process of GPR is complex and takes a long time. It can be seen from the above that the ...
