KPCA and AE Based Local-Global Feature Extraction Method for Vibration Signals of Rotating Machinery
Feature extraction plays a key role in fault diagnosis of rotating machinery. Many methods reported in the literature are based on masses of labeled data and need much prior knowledge to select the most discriminating features or establish a complex deep-learning model. To solve the dilemma, a novel...
