Variational Autoencoders Pursue PCA Directions (by Accident) [PDF]

open access: yesComputer Vision and Pattern Recognition, 2018
The Variational Autoencoder (VAE) is a powerful architecture capable of representation learning and generative modeling. When it comes to learning interpretable (disentangled) representations, VAE and its variants show unparalleled performance.

Scaled PCA: A New Approach to Dimension Reduction

open access: yesManagement 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 ...

DWT/PCA face recognition using automatic coefficient selection [PDF]

open access: yes, 2008
In PCA-based face recognition, there is often a trade-off between selecting the most relevant parts of a face image for recognition and not discarding information which may be useful.
