Applications of Online Nonnegative Matrix Factorization to Image and Time-Series Data
Hanbaek Lyu, Georg Menz, Deanna Needell +1
Online nonnegative matrix factorization (ONMF) is a matrix factorization technique in the online setting where data are acquired in a streaming fashion and the matrix factors are u…
Hydrodynamic limit of the Kawasaki dynamics on the 1D-lattice with strong, finite-range interaction
Younghak Kwon, Georg Menz, Kyeongsik Nam
We derive the hydrodynamic limit of the Kawasaki dynamics for the one-dimensional conservative system of unbounded real-valued spins with arbitrary strong, quadratic and finite-ran…
COVID-19 Time-series Prediction by Joint Dictionary Learning and Online NMF
Hanbaek Lyu, Christopher Strohmeier, Georg Menz +1
Predicting the spread and containment of COVID-19 is a challenge of utmost importance that the broader scientific community is currently facing. One of the main sources of difficul…
Equivalence of the grand canonical ensemble and the canonical ensemble on 1d-lattice systems
Younghak Kwon, Jaehun Lee, Georg Menz
We consider a one-dimensional lattice system of unbounded, real-valued spins with arbitrary strong, quadratic, finite-range interaction. We show the equivalence of the grand canoni…
Deducing a variational principle with minimal a priori assumptions
Andrew Krieger, Georg Menz, Martin Tassy
We study the well-known variational and large deviation principle for graph homomorphisms from to . We provide a robust method to deduce those principles…
Metastability in a continuous mean-field model at low temperature and strong interaction
Kaveh Bashiri, Georg Menz
We consider a system of mean-field interacting stochastic differential equations that are driven by a single-site potential of double-well form and by Brownian…
