A continuous symmetry breaking measure for finite clusters using Jensen-Shannon divergence
Ling Lan, Qiang Du, Simon J. L. Billinge
A quantitative measure of symmetry breaking is introduced that allows the quantification of which symmetries are most strongly broken due to the introduction of some kind of defect…
Stretched Non-negative Matrix Factorization
Ran Gu, Yevgeny Rakita, Ling Lan +9
An algorithm is described and tested that carries out a non negative matrix factorization (NMF) ignoring any stretching of the signal along the axis of the independent variable. Th…
Robustness test of the spacegroupMining model for determining space groups from atomic pair distribution function data
Ling Lan, Chia-Hao Liu, Qiang Du +1
Machine learning models based on convolutional neural networks have been used for predicting space groups of crystal structures from their atomic pair distribution function (PDF).…
A fast two-stage algorithm for non-negative matrix factorization in streaming data
Ran Gu, Qiang Du, Simon J. L. Billinge
In this article, we study algorithms for nonnegative matrix factorization (NMF) in various applications involving streaming data. Utilizing the continual nature of the data, we dev…
