Hierarchical Compound Poisson Factorization
Mehmet E. Basbug, Barbara E. Engelhardt
Non-negative matrix factorization models based on a hierarchical Gamma-Poisson structure capture user and item behavior effectively in extremely sparse data sets, making them the i…
Fast moment estimation for generalized latent Dirichlet models
Shiwen Zhao, Barbara E. Engelhardt, Sayan Mukherjee +1
We develop a generalized method of moments (GMM) approach for fast parameter estimation in a new class of Dirichlet latent variable models with mixed data types. Parameter estimati…
Adaptive Randomized Dimension Reduction on Massive Data
Gregory Darnell, Stoyan Georgiev, Sayan Mukherjee +1
The scalability of statistical estimators is of increasing importance in modern applications. One approach to implementing scalable algorithms is to compress data into a low dimens…
