In this paper, we introduce an advanced age determination technique that combines a feature set derived from an image of the face using multi-factored Principal Components Analysis (PCA) on the shape of the face and its features and the skin of the face to produce a 30 × 1 linear encoding of the face. The linearly encoded features are combined with Spectral Regression (SR) to improve performance of...
Visible and near infrared spectroscopy (Vis/NIR) combined with chemometric methods was employed to classify rice wines with different ages. Spectra of 240 wine samples (80 for each year) were collected in the Vis/NIR region (325-1075nm) in the spectroradiometer in transmission mode. Partial least squares (PLS) analysis was applied to extract the principal components (PCs) as new eigenvectors to represent...
The aim of this paper is to monitor the bearing damage developing by vibration signals measured from induction motors subjected to bearing fluting aging. The vibration signals taken from the accelerometers were analyzed by principal component analysis (PCA) and computed their spectra to denote the progressing of the aging. Meanwhile, using the principal component (PC) results, the entropy values based...
