Abstract :
Principal component analysis in the frequency domain is used for neural identification of the radiated noise from ships. For comparison, components are extracted from three different approaches: linear (PCA) and nonlinear (NLPCA) principal component analysis, and neural discriminating analysis (NDA). The classifier using NDA achieves a classification efficiency of about 93% using only 3 components, while the classifiers using PCA and NLPCA need up to 33 components to reach the same efficiency
