Doubly Non-Central Beta Matrix Factorization for DNA Methylation Data
Aaron Schein, Anjali Nagulpally, Hanna Wallach +1
We present a new non-negative matrix factorization model for bounded-support data based on the doubly non-central beta (DNCB) distribution, a generalization of the beta dis…

MAP Clustering under the Gaussian Mixture Model via Mixed Integer Nonlinear Optimization
Patrick Flaherty, Pitchaya Wiratchotisatian, Ji Ah Lee +2
We present a global optimization approach for solving the maximum a-posteriori (MAP) clustering problem under the Gaussian mixture model.Our approach can accommodate side constrain…
