Vertex misalignment and changepoint localization in network time series
Tianyi Chen, Mohammad Sharifi Kiasari, Sijing Yu +5
Inference for time series of networks often relies on accurate vertex correspondence between network realizations at different times. In practice, such vertex alignments can be mis…
KRAFTY: Khatri-Rao Framework for Joint Cluster Recovery
Siyi Gao, Zachary Lubberts, Marianna Pensky
When multiple datasets describe complementary information about the same set of entities, for example, brain scans of an individual over time, global trade network across years, or…
Limiting distributions of ratios of Binomial random variables
Adriel Barretto, Zachary Lubberts
We consider the limiting distribution of the quantity , where and are two independent Binomial random variables with a common success probability and a number…
Joint Spectral Clustering in Multilayer Degree-Corrected Stochastic Blockmodels
Joshua Agterberg, Zachary Lubberts, Jesús Arroyo
Modern network datasets are often composed of multiple layers, either as different views, time-varying observations, or independent sample units, resulting in collections of networ…
Entrywise Estimation of Singular Vectors of Low-Rank Matrices with Heteroskedasticity and Dependence
Joshua Agterberg, Zachary Lubberts, Carey Priebe
We propose an estimator for the singular vectors of high-dimensional low-rank matrices corrupted by additive subgaussian noise, where the noise matrix is allowed to have dependence…
