MATLAB Code Implementation for Computing Kernel Function Matrix

This documentation discusses multiple methods for computing kernel function matrices. The covered kernel functions include Gaussian kernel, Laplace kernel, polynomial kernel, hyperbolic polynomial kernel, spline kernel, Cauchy kernel, cubic kernel, radial basis function (RBF) kernel, thin plate spline (TPS) kernel, and bubble kernel.

Computing kernel function matrices is a crucial step in machine learning, as these matrices serve as the foundation for training models. Selecting appropriate kernel functions can significantly enhance model performance and accuracy, requiring careful consideration during the kernel selection process. In MATLAB implementations, each kernel function typically involves calculating pairwise similarities between data points using specific mathematical formulations - for instance, the Gaussian kernel uses exponential distance measures while polynomial kernels employ degree-based transformations. This documentation provides comprehensive information to help you better select suitable kernel functions and improve the performance of your machine learning models through optimized matrix computations.
