Title:
Linked Data Analysis without Linkage
Abstract:
Record Linkage (RL) is widely regarded as the gold standard for leveraging information scattered across multiple files. At the same time, RL can be tedious, error-prone, and privacy-invasive, which has hampered a more widespread and streamlined adoption. In this talk, I introduce Unlinked Data Analysis as a novel paradigm enabling inference for associations of variables across files, without linking them.
In the first part, I discuss the task of learning a map between d-dimensional inputs and d-dimensional noisy outputs, without observing (input, output)-pairs, but only separate unordered lists of inputs and outputs. I show that this problem can be solved for Brenier maps and present a practical algorithm for denoising based on the Kiefer-Wolfowitz nonparametric maximum likelihood estimator (NPMLE) and techniques from optimal transport. I provide upper bounds on the resulting mean squared denoising error under (i) Gaussian noise and (ii) noise from a certain class of elliptic distributions.
In the second part, I give an overview of linear regression in the unlinked setting, with a particular focus on existing results and open problems related to identifiability.
