Learning to predict synchronization of coupled oscillators on randomly generated graphs
Hardeep Bassi, Richard Yim, Rohith Kodukula +3
Suppose we are given a system of coupled oscillators on an unknown graph along with the trajectory of the system during some period. Can we predict whether the system will eventual…
Block majorization-minimization with diminishing radius for constrained nonsmooth nonconvex optimization
Hanbaek Lyu, Yuchen Li
Block majorization-minimization (BMM) is a simple iterative algorithm for constrained nonconvex optimization that sequentially minimizes majorizing surrogates of the objective func…
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…
Three-velocity coalescing ballistic annihilation
Luis Benitez, Matthew Junge, Hanbaek Lyu +2
Three-velocity ballistic annihilation is an interacting system in which stationary, left-, and right-moving particles are placed at random throughout the real line and mutually ann…
Sparseness-constrained Nonnegative Tensor Factorization for Detecting Topics at Different Time Scales
Lara Kassab, Alona Kryshchenko, Hanbaek Lyu +4
Temporal data (such as news articles or Twitter feeds) often consists of a mixture of long-lasting trends and popular but short-lasting topics of interest. A truly successful topic…
On the number of contingency tables and the independence heuristic
Hanbaek Lyu, Igor Pak
We obtain sharp asymptotic estimates on the number of contingency tables with two linear margins and . The results imply a second order phase transition on t…
Online nonnegative CP-dictionary learning for Markovian data
Hanbaek Lyu, Christopher Strohmeier, Deanna Needell
Online Tensor Factorization (OTF) is a fundamental tool in learning low-dimensional interpretable features from streaming multi-modal data. While various algorithmic and theoretica…
Stretched exponential decay for subcritical parking times on
Michael Damron, Hanbaek Lyu, David Sivakoff
In the parking model on , each vertex is initially occupied by a car (with probability ) or by a vacant parking spot (with probability ). Cars perform indepen…
Particle density in diffusion-limited annihilating systems
Tobias Johnson, Matthew Junge, Hanbaek Lyu +1
Place an -particle at each site of a graph independently with probability and otherwise place a -particle. - and -particles perform independent continuous time rand…
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…
