Research on Rolling Bearing Fault Diagnosis Based on Volterra Kernel Identification and KPCA

open access: yesShock and Vibration, 2023
A rolling bearing fault diagnosis method based on the Volterra series and kernel principal component analysis (KPCA) is proposed. In the proposed method, first, the improved genetic algorithm (IGA) is used to identify the Volterra series model of the ...

Kernel principal component analysis (KPCA) for the de-noising of communication signals [PDF]

open access: yes, 2002
This paper is concerned with the problem of de-noising for non-linear signals. Principal Component Analysis (PCA) cannot be applied to non-linear signals however it is known that using kernel functions, a non-linear signal can be transformed into a ...

Nonlinear process fault detection and identification using kernel PCA and kernel density estimation [PDF]

open access: yes, 2016
Kernel principal component analysis (KPCA) is an effective and efficient technique for monitoring nonlinear processes. However, associating it with upper control limits (UCLs) based on the Gaussian distribution can deteriorate its performance.

Streaming Kernel Principal Component Analysis

open access: yesCoRR, 2015
Kernel principal component analysis (KPCA) provides a concise set of basis vectors which capture non-linear structures within large data sets, and is a central tool in data analysis and learning. To allow for non-linear relations, typically a full $n \times n$ kernel matrix is constructed over $n$ data points, but this requires too much space and time ...

Dynamic gesture recognition using PCA with multi-scale theory and HMM [PDF]

open access: yes, 2001
In this paper, a dynamic gesture recognition system is presented which requires no special hardware other than a Webcam. The system is based on a novel method combining Principal Component Analysis (PCA) with hierarchical multi-scale theory and Discrete ...

Weighted SNP set analysis in genome-wide association study. [PDF]

open access: yesPLoS ONE, 2013
Genome-wide association studies (GWAS) are popular for identifying genetic variants which are associated with disease risk. Many approaches have been proposed to test multiple single nucleotide polymorphisms (SNPs) in a region simultaneously which ...
