On Differentially Private U Statistics
Kamalika Chaudhuri, Po-Ling Loh, Shourya Pandey +1
We consider the problem of privately estimating a parameter , where , , , are i.i.d. data from some distribution and is a p…
On the identifiability of mixtures of ranking models
Xiaomin Zhang, Xucheng Zhang, Po-Ling Loh +1
Mixtures of ranking models are standard tools for ranking problems. However, even the fundamental question of parameter identifiability is not fully understood: the identifiability…
On model misspecification and KL separation for Gaussian graphical models
Varun Jog, Po-Ling Loh
We establish bounds on the KL divergence between two multivariate Gaussian distributions in terms of the Hamming distance between the edge sets of the corresponding graphical model…
Statistical consistency and asymptotic normality for high-dimensional robust M-estimators
Po-Ling Loh
We study theoretical properties of regularized robust M-estimators, applicable when data are drawn from a sparse high-dimensional linear model and contaminated by heavy-tailed dist…
Support recovery without incoherence: A case for nonconvex regularization
Po-Ling Loh, Martin J. Wainwright
We demonstrate that the primal-dual witness proof method may be used to establish variable selection consistency and -bounds for sparse regression problems, even when…
Concavity of reweighted Kikuchi approximation
Po-Ling Loh, Andre Wibisono
We analyze a reweighted version of the Kikuchi approximation for estimating the log partition function of a product distribution defined over a region graph. We establish sufficien…
