Implementation of fault detection using kernel principal component analysis with custom-developed program that achieves excellent performance after minor modifications

Detailed Documentation

We implement fault detection using kernel principal component analysis (KPCA). This method leverages data mining techniques to effectively analyze data and extract valuable information. Our custom-developed program implements KPCA through several key components: kernel function selection (typically radial basis function), eigenvalue decomposition of the kernel matrix, and calculation of statistical indices (such as T² and SPE statistics) for fault detection. After minor parameter tuning and optimization, the program demonstrates excellent performance in various applications. This method can be applied across multiple domains including industrial systems, healthcare monitoring, and financial analytics to enhance problem identification and resolution capabilities. The implementation involves dimensionality reduction through nonlinear transformation and monitoring of process behavior using statistical control limits.
