Worst-case vs Average-case Design for Estimation from Fixed Pairwise Comparisons
Ashwin Pananjady, Cheng Mao, Vidya Muthukumar +2
Pairwise comparison data arises in many domains, including tournament rankings, web search, and preference elicitation. Given noisy comparisons of a fixed subset of pairs of items,…
Denoising Linear Models with Permuted Data
Ashwin Pananjady, Martin J. Wainwright, Thomas A. Courtade
The multivariate linear regression model with shuffled data and additive Gaussian noise arises in various correspondence estimation and matching problems. Focusing on the denoising…
Existence of Stein Kernels under a Spectral Gap, and Discrepancy Bound
Thomas A. Courtade, Max Fathi, Ashwin Pananjady
We establish existence of Stein kernels for probability measures on satisfying a Poincaré inequality, and obtain bounds on the Stein discrepancy of such measures. Ap…
Information-Theoretic Perspectives on Brascamp-Lieb Inequality and Its Reverse
Jingbo Liu, Thomas A. Courtade, Paul Cuff +1
We introduce an inequality which may be viewed as a generalization of both the Brascamp-Lieb inequality and its reverse (Barthe's inequality), and prove its information-theoretic (…
