Conic Scan-and-Cover algorithms for nonparametric topic modeling
Mikhail Yurochkin, Aritra Guha, XuanLong Nguyen
We propose new algorithms for topic modeling when the number of topics is unknown. Our approach relies on an analysis of the concentration of mass and angular geometry of the topic…
Multi-way Interacting Regression via Factorization Machines
Mikhail Yurochkin, XuanLong Nguyen, Nikolaos Vasiloglou
We propose a Bayesian regression method that accounts for multi-way interactions of arbitrary orders among the predictor variables. Our model makes use of a factorization mechanism…
Robust estimation of mixing measures in finite mixture models
Nhat Ho, XuanLong Nguyen, Ya'acov Ritov
In finite mixture models, apart from underlying mixing measure, true kernel density function of each subpopulation in the data is, in many scenarios, unknown. Perhaps the most popu…
Multilevel Clustering via Wasserstein Means
Nhat Ho, XuanLong Nguyen, Mikhail Yurochkin +3
We propose a novel approach to the problem of multilevel clustering, which aims to simultaneously partition data in each group and discover grouping patterns among groups in a pote…
Learning Models over Relational Data using Sparse Tensors and Functional Dependencies
Mahmoud Abo Khamis, Hung Q. Ngo, XuanLong Nguyen +2
Integrated solutions for analytics over relational databases are of great practical importance as they avoid the costly repeated loop data scientists have to deal with on a daily b…
