Convex and Semi-Nonnegative Matrix Factorizations

TL;DR: This work considers factorizations of the form X = FGT, and focuses on algorithms in which G is restricted to containing nonnegative entries, but allowing the data matrix X to have mixed signs, thus extending the applicable range of NMF methods.
Proceedings ArticleDOI

Orthogonal nonnegative matrix t-factorizations for clustering

TL;DR: This work provides a new approach of evaluating the quality of clustering on words using class aggregate distribution and multi-peak distribution and provides new rules for updating $F,S, G$ and proves the convergence of these algorithms.
Journal ArticleDOI

Modeling Linkage Disequilibrium Increases Accuracy of Polygenic Risk Scores

Bjarni J. Vilhjálmsson, +394 more
TL;DR: LDpred is introduced, a method that infers the posterior mean effect size of each marker by using a prior on effect sizes and LD information from an external reference panel, and outperforms the approach of pruning followed by thresholding, particularly at large sample sizes.

A broadband achromatic metalens in the visible

TL;DR: Integrating the Pancharatnam–Berry phase with integrated resonant nanoantennas in a metalens design produces an achromatic device capable of full-colour imaging in the visible range in transmission mode.
