First-passage percolation on a width-2 strip and the path cost in a VCG auction
TL;DR: These statistics attempt to describe two seemingly unrelated phenomena, arising in physics and economics respectively: the first-passage percolation time predicts how long it takes for a fluid to spread through a random medium, while the VCG payment for the shortest path is the cost of maximizing social welfare among selfish agents.

First-passage percolation on a width-2 strip and the path cost in a VCG auction
TL;DR: In this paper, the Vickery-Clarke-Groves (VCG) payment for the shortest path on a width-2 strip with random edge costs is analyzed, and the first-passage percolation time predicts how long it takes for a fluid to spread through a random medium, while the VCG payment is the cost of maximizing social welfare among selfish agents.
Journal ArticleDOI
Differential privacy in the 2020 US census: what will it do? Quantifying the accuracy/privacy tradeoff.
TL;DR: An empirical measure of privacy loss is developed to compare the error and privacy of the new approach to that of a (non-differentially private) simple-random-sampling approach to protecting privacy and it is found that the empirical privacy loss of TopDown is substantially smaller than the theoretical guarantee for all privacy loss budgets.
Proceedings ArticleDOI
On the average case performance of some greedy approximation algorithms for the uncapacitated facility location problem
TL;DR: This paper analyzes the performance of 3 related approximation algorithms for the uncapacitated facility location problem and finds that, with high probability, these 3 algorithms do not find asymptotically optimal solutions, and a simple plane partitioning heuristic does find an asymptonically optimal solution.
Journal ArticleDOI
The paradox of verbal autopsy in cause of death assignment: symptom question unreliability but predictive accuracy

TL;DR: Families give coherent accounts of events leading to death but the details vary from interview to interview for the same case, which has considerable implications for the progressive roll out of VAs into civil registration and vital statistics systems.
