The Antioxidant Activity of Maltese Honey
Journal of Apicultural Science, 2014 Maltese honey has been valued for its medicinal properties since ancient times, so much so that the word Malta is derived from the ancient Greek word, Melite, which means honey. In this study, Maltese honey samples (n = 30) from three harvest seasons and

Scaled PCA: A New Approach to Dimension Reduction
Management Sciences, 2019 This paper proposes a novel supervised learning technique for forecasting: scaled principal component analysis (sPCA). The sPCA improves the traditional principal component analysis (PCA) by scaling each predictor with its predictive slope on the target ...

$e$PCA: High dimensional exponential family PCA
The Annals of Applied Statistics, 2018 Many applications, such as photon-limited imaging and genomics, involve large datasets with noisy entries from exponential family distributions. It is of interest to estimate the covariance structure and principal components of the noiseless distribution.

Validation of Nonlinear PCA [PDF]
Neural Processing Letters, 2012 Linear principal component analysis (PCA) can be extended to a nonlinear PCA by using artificial neural networks. But the benefit of curved components requires a careful control of the model complexity. Moreover, standard techniques for model selection, including cross-validation and more generally the use of an independent test set, fail when applied ...
