In this paper we use bearing data as a test bed for dimensionality reduction methods based in latent variable modeling, in which an underlying lower dimension representation is inferred directly from the data, and apply it to the classification of bearing fault. The optimization of GTM processing experiential parameters, which consist of the number of latent points and basis function, a width parameter...
A novel method of pattern recognition and fault diagnosis in roll bearing based on the wavelet-neural network is proposed according to the frequency spectrum characteristics of vibration signal. Based on the advantage of multi-dimensional multi-scaling decomposition of wavelet packets, the abrupt change information can be obtained and the features related to the fault of roll bearing is extracted...
This paper focuses on the application of self-organizing maps (SOM) in motor bearing fault diagnosis and presents an approach for motor rolling bearing fault diagnosis using SOM neural networks and time/frequency-domain bearing analysis. The SOM is a neural network algorithm which is based on unsupervised learning and combines the tasks of vector quantization and data projection. The objective of...
