Supervised Health Stage Prediction Using Convolutional Neural Networks for Bearing Wear

Early detection of faults in rotating machinery systems is crucial in preventing system failure, increasing safety, and reducing maintenance costs. Current methods of fault detection suffer from the lack of efficient feature extraction method, the need for designating a threshold producing minimal f...
