BP neural network bearing
no vote
Bearing fault feature extraction is closely related to the accuracy of diagnosis, and its methods are constantly improving, such as traditional indicators, talaf and Thika indicators. In this paper, the kernel principal component analysis (KPCA) feature extraction method based on particle swarm optimization (PSO) is used.

Local mean decomposition
no vote
The program from Dashen has been studied for half a year, and some improvements have been made in some places to solve the problem of mode aliasing in local mean decomposition, but only for some sine and cosine signals. I hope Dashen in the forum can give some advice.
