Fault detection method using k nearest neighbor rule has shown its advantages in dealing with nonlinear, multi-mode, and nonGaussian distributed data. Once a fault is detected in industrial processes, recognizing fault variables becomes the crucial task subsequently. Recently, the method of fault variables recognition using k nearest neighbor reconstruction (FVR-kNN) has been reported. However, the...
Prognostics and health management is an emerging engineering technology that has been applied to a large variety of engineering systems to improve system's reliability. However, existing prognostics approaches have been developed largely based upon specific applications and system models, thus possess limited general applicability. This paper presents a generic data-driven prognostics method, namely...
