Imbalanced Data Fault Diagnosis Based on an Evolutionary Online Sequential Extreme Learning Machine

To quickly and effectively identify an axle box bearing fault of high-speed electric multiple units (EMUs), an evolutionary online sequential extreme learning machine (OS-ELM) fault diagnosis method for imbalanced data was proposed. In this scheme, the resampling scale is first determined according...
