Automatic Relevance Determination in Nonnegative Matrix Factorization with the β-Divergence
Vincent Y. F. Tan, Cédric Févotte
This paper addresses the estimation of the latent dimensionality in nonnegative matrix factorization (NMF) with the β-divergence. The β-divergence is a family of cost functions tha…
Moderate-Deviations of Lossy Source Coding for Discrete and Gaussian Sources
Vincent Y. F. Tan
We study the moderate-deviations (MD) setting for lossy source coding of stationary memoryless sources. More specifically, we derive fundamental compression limits of source codes…
Canonical Estimation in a Rare-Events Regime
Mesrob I. Ohannessian, Vincent Y. F. Tan, Munther A. Dahleh
We propose a general methodology for performing statistical inference within a `rare-events regime' that was recently suggested by Wagner, Viswanath and Kulkarni. Our approach allo…
The Sender-Excited Secret Key Agreement Model: Capacity, Reliability and Secrecy Exponents
Tzu-Han Chou, Vincent Y. F. Tan, Stark C. Draper
We consider the secret key generation problem when sources are randomly excited by the sender and there is a noiseless public discussion channel. Our setting is thus similar to rec…
High-dimensional structure estimation in Ising models: Local separation criterion
Animashree Anandkumar, Vincent Y. F. Tan, Furong Huang +1
We consider the problem of high-dimensional Ising (graphical) model selection. We propose a simple algorithm for structure estimation based on the thresholding of the empirical con…
High-Dimensional Gaussian Graphical Model Selection: Walk Summability and Local Separation Criterion
Animashree Anandkumar, Vincent Y. F. Tan, Alan. S. Willsky
We consider the problem of high-dimensional Gaussian graphical model selection. We identify a set of graphs for which an efficient estimation algorithm exists, and this algorithm i…
