Estimating Divergence Functionals and the Likelihood Ratio by Convex Risk Minimization

- X. Nguyen, M. Wainwright, Michael I. Jordan
- Mathematics, Computer Science
- IEEE Transactions on Information Theory
- 4 September 2008

We develop and analyze M-estimation methods for divergence functionals and the likelihood ratios of two probability distributions. Our method is based on a nonasymptotic variational characterization… Expand

Convergence of latent mixing measures in finite and infinite mixture models

- X. Nguyen
- Mathematics
- 15 September 2011

This paper studies convergence behavior of latent mixing measures that arise in finite and infinite mixture models, using transportation distances (i.e., Wasserstein metrics). The relationship… Expand

Reviving Partial Order Planning

- X. Nguyen, S. Kambhampati
- Mathematics, Computer Science
- IJCAI
- 4 August 2001

This paper challenges the prevailing pessimism about the scalability of partial order planning (POP) algorithms by presenting several novel heuristic control techniques that make them competitive… Expand

Nonparametric decentralized detection using kernel methods

- X. Nguyen, M. Wainwright, M.I. Jordan
- Mathematics
- IEEE Transactions on Signal Processing
- 1 November 2005

We consider the problem of decentralized detection under constraints on the number of bits that can be transmitted by each sensor. In contrast to most previous work, in which the joint distribution… Expand
