Training Recurrent Neural Networks Using Optimization Layer-by- Layer Recursive Least Squares Algorithm for Vibration Signals System Identification and Fault Diagnostic Analysis
2001
Journal of Intelligent Systems
Preserved Fulltext
Depending on the representation ability and the dynamic capability of recurrent neural networks for nonlinear models, a neural-based approach for general practical nonlinear systems identification is demonstrated ...
The proposed neural-based approach is also applied to the railway carriage system identification by identifying the train vibration signal. ...
In accordance with this property, a railway carriage system identification based on a neural network model is valuable for an on-line railway carriage conditions monitoring system. ...
