Orthogonality Loss: Learning Discriminative Representations for Face Recognition

IEEE transactions on circuits and systems for video technology (Print), 2021
Convolutional neural networks have achieved excellent performance on face recognition (FR) by learning the high discriminative features with advanced loss functions. These improved loss functions share the similar idea for maximizing inter-class variance

Separation orthogonality in liquid chromatography-mass spectrometry for proteomic applications: comparison of 16 different two-dimensional combinations.

Analytical Chemistry, 2020
Peptide separation orthogonality for 16 different 2D LC-ESI MS systems has been evaluated. To compare and contrast the behavior of the first dimension columns, a large proteomic retention dataset of ~30,000 tryptic peptides was collected for each 2D ...

Orthogonal sets; orthogonal contractions

Asian-European Journal of Mathematics, 2019
In this paper, we are interested in obtaining fixed point theorems by keeping the orthogonal completeness of the orthogonal metric space and replacing the [Formula: see text]-contraction condition in theorems by another slightly modified conditions. The paper contains an example illustrating our results.

Orthogonalization Methods

Journal of Mathematical Physics, 1970
An essentially unique method of forming an orthonormalized set of vectors from an independent set of n vectors is presented. The resulting set is proven to maximize a certain quartic form in the original vectors.
