Pumping Unit Fault Diagnosis Method Based on Semi-supervised Manifold Learning
ZHAO Wanping
Abstract：According to indicator diagram of known samples in actual production of oil is deficient,A semi supervised recogni?tion method based on manifold learning is proposed. Low-dimensional feature space can be obtained using manifold learning algo?rithm by labeled and unlabeled sample data to the data collected for feature extraction. It can achieve the purpose of fault diagnosis in the low-dimensional feature space for fault pattern classification,and achieve good effect in practical application.
