Geometric planted matchings in high dimensions: The power of multiple views

Timothy L. H. Wee, Kaylee Y. Yang, Zhou Fan +1

We study the problem of recovering the correspondence between a collection of $n$ points in $R^{d}$ and a noisy, permuted version of those points. In the high-dimensional re…

Convergence of the Inexact Langevin Algorithm in KL Divergence with Application to Score-based Generative Models

Kaylee Yingxi Yang, Andre Wibisono

Motivated by the increasingly popular Score-based Generative Modeling (SGM), we study the Inexact Langevin Dynamics (ILD) and Inexact Langevin Algorithm (ILA) where a score functio…

Bayesian inference of planted matchings: Local posterior approximation and infinite-volume limit

Zhou Fan, Timothy L. H. Wee, Kaylee Y. Yang

We study Bayesian inference of an unknown matching $I ¨ ^{*}$ between two correlated random point sets ${X_{i}}_{i = 1}^{n}$ and ${Y_{i}}_{i = 1}^{n}$ in $[0, 1]^{d}$ , under a critical scaling $\…

Asymptotic mutual information in quadratic estimation problems over compact groups

Kaylee Y. Yang, Timothy L. H. Wee, Zhou Fan

Motivated by applications to group synchronization and quadratic assignment on random data, we study a general problem of Bayesian inference of an unknown ``signal'' belonging to a…
