A New Unsupervised Online Early Fault Detection Framework of Rolling Bearings Based on Granular Feature Forecasting

In online scenarios, the monitoring signals are collected in the form of streaming data and would raise some requirements for early fault detection (EFD) of rolling bearings: 1) enhancing the detection accuracy of online data; 2) lowering the computational cost of real-time detection; 3) reducing fa...
