Population-Based Hierarchical Non-negative Matrix Factorization for Survey Data
Xiaofu Ding, Xinyu Dong, Olivia McGough +6
Motivated by the problem of identifying potential hierarchical population structure on modern survey data containing a wide range of complex data types, we introduce population-bas…
SP2: A Second Order Stochastic Polyak Method
Shuang Li, William J. Swartworth, Martin Takáč +2
Recently the "SP" (Stochastic Polyak step size) method has emerged as a competitive adaptive method for setting the step sizes of SGD. SP can be interpreted as a method specialized…
Testing Positive Semidefiniteness Using Linear Measurements
Deanna Needell, William Swartworth, David P. Woodruff
We study the problem of testing whether a symmetric input matrix is symmetric positive semidefinite (PSD), or is -far from the PSD cone, meaning that $λ_{\min}(…
