Unsupervised robust nonparametric learning of hidden community properties
Mikhail A. Langovoy, Akhilesh Gotmare, Martin Jaggi
We consider learning of fundamental properties of communities in large noisy networks, in the prototypical situation where the nodes or users are split into two classes according t…
An Alternative to EM for Gaussian Mixture Models: Batch and Stochastic Riemannian Optimization
Reshad Hosseini, Suvrit Sra
We consider maximum likelihood estimation for Gaussian Mixture Models (Gmms). This task is almost invariably solved (in theory and practice) via the Expectation Maximization (EM) a…
Polynomial Time Algorithms for Dual Volume Sampling
Chengtao Li, Stefanie Jegelka, Suvrit Sra
We study dual volume sampling, a method for selecting k columns from an n x m short and wide matrix (n <= k <= m) such that the probability of selection is proportional to the volu…
