Detailed Documentation
Below, I present MATLAB code for performing Kernel Principal Component Analysis (KPCA) with a polynomial kernel function. The implementation includes comprehensive comments to facilitate understanding. It's important to note that KPCA is a powerful technique for nonlinear dimensionality reduction and data visualization, particularly useful when dealing with complex, non-linearly separable datasets. The code demonstrates key steps including kernel matrix computation, eigenvalue decomposition, and projection of data into the principal component space. The polynomial kernel function allows capturing higher-order feature interactions through its degree parameter, making it suitable for various machine learning applications.
