Location: 232A Withers Hall, NC State Main Campus Title: Multivariate spatial models for high-dimensional ecological data Presenter: Jeffrey W. Doser, Ph.D. Abstract: The proliferation of big spatial data from autonomous monitoring systems, national monitoring programs, and citizen science platforms offers never-before-seen opportunities to address pressing natural resource management and conservation questions. Yet, such massive spatial…

Location: 232A Withers Hall, NC State Main Campus Title: Finding Anomalous Cliques in Inhomogeneous Networks using Egonets Presenter:  Srijan Sengupta Abstract: Cliques, or fully connected subgraphs, are among the most important and well-studied graph motifs in network science. We consider the problem of finding a statistically anomalous clique hidden in a large network. There are two…

Location: 232A Withers Hall, NC State Main Campus Title: Rotated Mean-Field Variational Inference and Iterative Gaussianization Presenter: Sifan Liu Abstract: Mean-field variational inference (MFVI) approximates a target distribution with a product distribution in the standard coordinate system, offering a scalable approach to Bayesian inference but often severely underestimating uncertainty due to neglected dependence. We show…
