Detailed Documentation
This MATLAB program implements both standard Independent Component Analysis (ICA) and Kernel-based Independent Component Analysis (KICA) algorithms. The implementation utilizes optimized matrix operations and parallel processing techniques to achieve significant computational efficiency. Experimental validation was conducted using the ORL face database, where the algorithms demonstrated fast convergence and high accuracy in image feature extraction and signal separation tasks. The code includes functions for data preprocessing, kernel matrix computation (for KICA), and component visualization, providing robust support for research in blind source separation and pattern recognition applications. Benchmark tests confirm the implementation's superior performance in processing high-dimensional datasets while maintaining analytical precision.
